Issue:
Avoid sequental route matching
Inputs:
 - AVG API has 20-30 endpoints
 - Almost all frameworks use sequential matching.
 - If the latest registered endpoints are the most frequently used, they are affected

Benchmark for 100_000 calls for 20 endpoints pattern matching:

```
30 Queries, SEQ, 30 matched 0.9767985000000001
30 Queries, SEQ, 20 matched 0.6514065000000001
30 Queries, SEQ, 10 matched 0.3275345000000001
30 Queries, SEQ, 3 matched 0.0948165
30 Queries, SEQ, 1 matched 0.026672500000000023
```

The router must be reworked using the following approach.
During route registration, we create records for furrowing structure (Example, TBD):

```
from sys import intern

route = {
  intern("api"): {
    intern("v1"): {
      intern("company"): {
        intern("_dyn"): "/api/v1/company/{company_id}"
      },
      intern("_dyn"): {
        intern("members"): {
          intern("_dyn"): {
            intern("edit"): "/api/v1/{some_dyn_attr}/members/{member_id}/edit"
          }
        }
      }
    }
  }
}
``` 

"_dyn" key represents a pattern part.

Lookup example:

```
def func(path, routes):
    last = routes
    dyn = intern("_dyn")
    for key in path:
        last = last.get(key) or last[dyn]
    return last

a = [intern(i) for i in ["api", "v1", "1321", "members", "2", "edit"]]
print("Lookup:", (timeit(lambda: func(a, route), number=100_000) - base))
```

`Lookup: 0.04070829999999997` - added time to single record pattern-matching.

There is an option to speed up this function even more (out of the scope of the current task).

-## Requirements
-
-Python 3.6+
-
-Squall stands on the shoulders of giants:
-
-* <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> for the web parts.
-* <a href="https://pydantic-docs.helpmanual.io/" class="external-link" target="_blank">Pydantic</a> for the data parts.
-
-## Installation
-
-<div class="termy">
-
-```console
-$ pip install squall
-
----> 100%
-```
-
-</div>
-
-You will also need an ASGI server, for production such as <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a> or <a href="https://gitlab.com/pgjones/hypercorn" class="external-link" target="_blank">Hypercorn</a>.
-
-<div class="termy">
-
-```console
-$ pip install "uvicorn[standard]"
-
----> 100%
-```
-
-</div>
-
-## Example
-
-### Create it
-
-* Create a file `main.py` with:
-
-```Python
-from typing import Optional
-
-from squall import Squall
-
-app = Squall()
-
-
-@app.get("/")
-def read_root():
-    return {"Hello": "World"}
-
-
-@app.get("/items/{item_id}")
-def read_item(item_id: int, q: Optional[str] = None):
-    return {"item_id": item_id, "q": q}
-```
-
-<details markdown="1">
-<summary>Or use <code>async def</code>...</summary>
-
-If your code uses `async` / `await`, use `async def`:
-
-```Python hl_lines="9  14"
-from typing import Optional
-
-from squall import Squall
-
-app = Squall()
-
-
-@app.get("/")
-async def read_root():
-    return {"Hello": "World"}
-
-
-@app.get("/items/{item_id}")
-async def read_item(item_id: int, q: Optional[str] = None):
-    return {"item_id": item_id, "q": q}
-```
-
-**Note**:
-
-If you don't know, check the _"In a hurry?"_ section about <a href="https://squall.mtag.dev/async/#in-a-hurry" target="_blank">`async` and `await` in the docs</a>.
-
-</details>
-
-### Run it
-
-Run the server with:
-
-<div class="termy">
-
-```console
-$ uvicorn main:app --reload
-
-INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
-INFO:     Started reloader process [28720]
-INFO:     Started server process [28722]
-INFO:     Waiting for application startup.
-INFO:     Application startup complete.
-```
-
-</div>
-
-<details markdown="1">
-<summary>About the command <code>uvicorn main:app --reload</code>...</summary>
-
-The command `uvicorn main:app` refers to:
-
-* `main`: the file `main.py` (the Python "module").
-* `app`: the object created inside of `main.py` with the line `app = Squall()`.
-* `--reload`: make the server restart after code changes. Only do this for development.
-
-</details>
-
-### Check it
-
-Open your browser at <a href="http://127.0.0.1:8000/items/5?q=somequery" class="external-link" target="_blank">http://127.0.0.1:8000/items/5?q=somequery</a>.
-
-You will see the JSON response as:
-
-```JSON
-{"item_id": 5, "q": "somequery"}
-```
-
-You already created an API that:
-
-* Receives HTTP requests in the _paths_ `/` and `/items/{item_id}`.
-* Both _paths_ take `GET` <em>operations</em> (also known as HTTP _methods_).
-* The _path_ `/items/{item_id}` has a _path parameter_ `item_id` that should be an `int`.
-* The _path_ `/items/{item_id}` has an optional `str` _query parameter_ `q`.
-
-### Interactive API docs
-
-Now go to <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.
-
-You will see the automatic interactive API documentation (provided by <a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank">Swagger UI</a>):
-
-![Swagger UI](https://squall.mtag.dev/img/index/index-01-swagger-ui-simple.png)
-
-### Alternative API docs
-
-And now, go to <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a>.
-
-You will see the alternative automatic documentation (provided by <a href="https://github.com/Rebilly/ReDoc" class="external-link" target="_blank">ReDoc</a>):
-
-![ReDoc](https://squall.mtag.dev/img/index/index-02-redoc-simple.png)
-
-## Example upgrade
-
-Now modify the file `main.py` to receive a body from a `PUT` request.
-
-Declare the body using standard Python types, thanks to Pydantic.
-
-```Python hl_lines="4  9-12  25-27"
-from typing import Optional
-
-from squall import Squall
-from pydantic import BaseModel
-
-app = Squall()
-
-
-class Item(BaseModel):
-    name: str
-    price: float
-    is_offer: Optional[bool] = None
-
-
-@app.get("/")
-def read_root():
-    return {"Hello": "World"}
-
-
-@app.get("/items/{item_id}")
-def read_item(item_id: int, q: Optional[str] = None):
-    return {"item_id": item_id, "q": q}
-
-
-@app.put("/items/{item_id}")
-def update_item(item_id: int, item: Item):
-    return {"item_name": item.name, "item_id": item_id}
-```
-
-The server should reload automatically (because you added `--reload` to the `uvicorn` command above).
-
-### Interactive API docs upgrade
-
-Now go to <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.
-
-* The interactive API documentation will be automatically updated, including the new body:
-
-![Swagger UI](https://squall.mtag.dev/img/index/index-03-swagger-02.png)
-
-* Click on the button "Try it out", it allows you to fill the parameters and directly interact with the API:
-
-![Swagger UI interaction](https://squall.mtag.dev/img/index/index-04-swagger-03.png)
-
-* Then click on the "Execute" button, the user interface will communicate with your API, send the parameters, get the results and show them on the screen:
-
-![Swagger UI interaction](https://squall.mtag.dev/img/index/index-05-swagger-04.png)
-
-### Alternative API docs upgrade
-
-And now, go to <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a>.
-
-* The alternative documentation will also reflect the new query parameter and body:
-
-![ReDoc](https://squall.mtag.dev/img/index/index-06-redoc-02.png)
-
-### Recap
-
-In summary, you declare **once** the types of parameters, body, etc. as function parameters.
-
-You do that with standard modern Python types.
-
-You don't have to learn a new syntax, the methods or classes of a specific library, etc.
-
-Just standard **Python 3.6+**.
-
-For example, for an `int`:
-
-```Python
-item_id: int
-```
-
-or for a more complex `Item` model:
-
-```Python
-item: Item
-```
-
-...and with that single declaration you get:
-
-* Editor support, including:
-    * Completion.
-    * Type checks.
-* Validation of data:
-    * Automatic and clear errors when the data is invalid.
-    * Validation even for deeply nested JSON objects.
-* <abbr title="also known as: serialization, parsing, marshalling">Conversion</abbr> of input data: coming from the network to Python data and types. Reading from:
-    * JSON.
-    * Path parameters.
-    * Query parameters.
-    * Cookies.
-    * Headers.
-    * Forms.
-    * Files.
-* <abbr title="also known as: serialization, parsing, marshalling">Conversion</abbr> of output data: converting from Python data and types to network data (as JSON):
-    * Convert Python types (`str`, `int`, `float`, `bool`, `list`, etc).
-    * `datetime` objects.
-    * `UUID` objects.
-    * Database models.
-    * ...and many more.
-* Automatic interactive API documentation, including 2 alternative user interfaces:
-    * Swagger UI.
-    * ReDoc.
-
----
-
-Coming back to the previous code example, **Squall** will:
-
-* Validate that there is an `item_id` in the path for `GET` and `PUT` requests.
-* Validate that the `item_id` is of type `int` for `GET` and `PUT` requests.
-    * If it is not, the client will see a useful, clear error.
-* Check if there is an optional query parameter named `q` (as in `http://127.0.0.1:8000/items/foo?q=somequery`) for `GET` requests.
-    * As the `q` parameter is declared with `= None`, it is optional.
-    * Without the `None` it would be required (as is the body in the case with `PUT`).
-* For `PUT` requests to `/items/{item_id}`, Read the body as JSON:
-    * Check that it has a required attribute `name` that should be a `str`.
-    * Check that it has a required attribute `price` that has to be a `float`.
-    * Check that it has an optional attribute `is_offer`, that should be a `bool`, if present.
-    * All this would also work for deeply nested JSON objects.
-* Convert from and to JSON automatically.
-* Document everything with OpenAPI, that can be used by:
-    * Interactive documentation systems.
-    * Automatic client code generation systems, for many languages.
-* Provide 2 interactive documentation web interfaces directly.
-
----
-
-We just scratched the surface, but you already get the idea of how it all works.
-
-Try changing the line with:
-
-```Python
-    return {"item_name": item.name, "item_id": item_id}
-```
-
-...from:
-
-```Python
-        ... "item_name": item.name ...
-```
-
-...to:
-
-```Python
-        ... "item_price": item.price ...
-```
-
-...and see how your editor will auto-complete the attributes and know their types:
-
-![editor support](https://squall.mtag.dev/img/vscode-completion.png)
-
-For a more complete example including more features, see the <a href="https://squall.mtag.dev/tutorial/">Tutorial - User Guide</a>.
-
-**Spoiler alert**: the tutorial - user guide includes:
-
-* Declaration of **parameters** from other different places as: **headers**, **cookies**, **form fields** and **files**.
-* How to set **validation constraints** as `maximum_length` or `regex`.
-* A very powerful and easy to use **<abbr title="also known as components, resources, providers, services, injectables">Dependency Injection</abbr>** system.
-* Security and authentication, including support for **OAuth2** with **JWT tokens** and **HTTP Basic** auth.
-* More advanced (but equally easy) techniques for declaring **deeply nested JSON models** (thanks to Pydantic).
-* **GraphQL** integration with <a href="https://strawberry.rocks" class="external-link" target="_blank">Strawberry</a> and other libraries.
-* Many extra features (thanks to Starlette) as:
-    * **WebSockets**
-    * extremely easy tests based on `requests` and `pytest`
-    * **CORS**
-    * **Cookie Sessions**
-    * ...and more.
-

-## Requirements
-
-Python 3.6+
-
-Squall stands on the shoulders of giants:
-
-* <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> for the web parts.
-* <a href="https://pydantic-docs.helpmanual.io/" class="external-link" target="_blank">Pydantic</a> for the data parts.
-
-## Installation
-
-<div class="termy">
-
-```console
-$ pip install squall
-
----> 100%
-```
-
-</div>
-
-You will also need an ASGI server, for production such as <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a> or <a href="https://gitlab.com/pgjones/hypercorn" class="external-link" target="_blank">Hypercorn</a>.
-
-<div class="termy">
-
-```console
-$ pip install "uvicorn[standard]"
-
----> 100%
-```
-
-</div>
-
-## Example
-
-### Create it
-
-* Create a file `main.py` with:
-
-```Python
-from typing import Optional
-
-from squall import Squall
-
-app = Squall()
-
-
-@app.get("/")
-def read_root():
-    return {"Hello": "World"}
-
-
-@app.get("/items/{item_id}")
-def read_item(item_id: int, q: Optional[str] = None):
-    return {"item_id": item_id, "q": q}
-```
-
-<details markdown="1">
-<summary>Or use <code>async def</code>...</summary>
-
-If your code uses `async` / `await`, use `async def`:
-
-```Python hl_lines="9  14"
-from typing import Optional
-
-from squall import Squall
-
-app = Squall()
-
-
-@app.get("/")
-async def read_root():
-    return {"Hello": "World"}
-
-
-@app.get("/items/{item_id}")
-async def read_item(item_id: int, q: Optional[str] = None):
-    return {"item_id": item_id, "q": q}
-```
-
-**Note**:
-
-If you don't know, check the _"In a hurry?"_ section about <a href="https://squall.mtag.dev/async/#in-a-hurry" target="_blank">`async` and `await` in the docs</a>.
-
-</details>
-
-### Run it
-
-Run the server with:
-
-<div class="termy">
-
-```console
-$ uvicorn main:app --reload
-
-INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
-INFO:     Started reloader process [28720]
-INFO:     Started server process [28722]
-INFO:     Waiting for application startup.
-INFO:     Application startup complete.
-```
-
-</div>
-
-<details markdown="1">
-<summary>About the command <code>uvicorn main:app --reload</code>...</summary>
-
-The command `uvicorn main:app` refers to:
-
-* `main`: the file `main.py` (the Python "module").
-* `app`: the object created inside of `main.py` with the line `app = Squall()`.
-* `--reload`: make the server restart after code changes. Only do this for development.
-
-</details>
-
-### Check it
-
-Open your browser at <a href="http://127.0.0.1:8000/items/5?q=somequery" class="external-link" target="_blank">http://127.0.0.1:8000/items/5?q=somequery</a>.
-
-You will see the JSON response as:
-
-```JSON
-{"item_id": 5, "q": "somequery"}
-```
-
-You already created an API that:
-
-* Receives HTTP requests in the _paths_ `/` and `/items/{item_id}`.
-* Both _paths_ take `GET` <em>operations</em> (also known as HTTP _methods_).
-* The _path_ `/items/{item_id}` has a _path parameter_ `item_id` that should be an `int`.
-* The _path_ `/items/{item_id}` has an optional `str` _query parameter_ `q`.
-
-### Interactive API docs
-
-Now go to <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.
-
-You will see the automatic interactive API documentation (provided by <a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank">Swagger UI</a>):
-
-![Swagger UI](https://squall.mtag.dev/img/index/index-01-swagger-ui-simple.png)
-
-### Alternative API docs
-
-And now, go to <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a>.
-
-You will see the alternative automatic documentation (provided by <a href="https://github.com/Rebilly/ReDoc" class="external-link" target="_blank">ReDoc</a>):
-
-![ReDoc](https://squall.mtag.dev/img/index/index-02-redoc-simple.png)
-
-## Example upgrade
-
-Now modify the file `main.py` to receive a body from a `PUT` request.
-
-Declare the body using standard Python types, thanks to Pydantic.
-
-```Python hl_lines="4  9-12  25-27"
-from typing import Optional
-
-from squall import Squall
-from pydantic import BaseModel
-
-app = Squall()
-
-
-class Item(BaseModel):
-    name: str
-    price: float
-    is_offer: Optional[bool] = None
-
-
-@app.get("/")
-def read_root():
-    return {"Hello": "World"}
-
-
-@app.get("/items/{item_id}")
-def read_item(item_id: int, q: Optional[str] = None):
-    return {"item_id": item_id, "q": q}
-
-
-@app.put("/items/{item_id}")
-def update_item(item_id: int, item: Item):
-    return {"item_name": item.name, "item_id": item_id}
-```
-
-The server should reload automatically (because you added `--reload` to the `uvicorn` command above).
-
-### Interactive API docs upgrade
-
-Now go to <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.
-
-* The interactive API documentation will be automatically updated, including the new body:
-
-![Swagger UI](https://squall.mtag.dev/img/index/index-03-swagger-02.png)
-
-* Click on the button "Try it out", it allows you to fill the parameters and directly interact with the API:
-
-![Swagger UI interaction](https://squall.mtag.dev/img/index/index-04-swagger-03.png)
-
-* Then click on the "Execute" button, the user interface will communicate with your API, send the parameters, get the results and show them on the screen:
-
-![Swagger UI interaction](https://squall.mtag.dev/img/index/index-05-swagger-04.png)
-
-### Alternative API docs upgrade
-
-And now, go to <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a>.
-
-* The alternative documentation will also reflect the new query parameter and body:
-
-![ReDoc](https://squall.mtag.dev/img/index/index-06-redoc-02.png)
-
-### Recap
-
-In summary, you declare **once** the types of parameters, body, etc. as function parameters.
-
-You do that with standard modern Python types.
-
-You don't have to learn a new syntax, the methods or classes of a specific library, etc.
-
-Just standard **Python 3.6+**.
-
-For example, for an `int`:
-
-```Python
-item_id: int
-```
-
-or for a more complex `Item` model:
-
-```Python
-item: Item
-```
-
-...and with that single declaration you get:
-
-* Editor support, including:
-    * Completion.
-    * Type checks.
-* Validation of data:
-    * Automatic and clear errors when the data is invalid.
-    * Validation even for deeply nested JSON objects.
-* <abbr title="also known as: serialization, parsing, marshalling">Conversion</abbr> of input data: coming from the network to Python data and types. Reading from:
-    * JSON.
-    * Path parameters.
-    * Query parameters.
-    * Cookies.
-    * Headers.
-    * Forms.
-    * Files.
-* <abbr title="also known as: serialization, parsing, marshalling">Conversion</abbr> of output data: converting from Python data and types to network data (as JSON):
-    * Convert Python types (`str`, `int`, `float`, `bool`, `list`, etc).
-    * `datetime` objects.
-    * `UUID` objects.
-    * Database models.
-    * ...and many more.
-* Automatic interactive API documentation, including 2 alternative user interfaces:
-    * Swagger UI.
-    * ReDoc.
-
----
-
-Coming back to the previous code example, **Squall** will:
-
-* Validate that there is an `item_id` in the path for `GET` and `PUT` requests.
-* Validate that the `item_id` is of type `int` for `GET` and `PUT` requests.
-    * If it is not, the client will see a useful, clear error.
-* Check if there is an optional query parameter named `q` (as in `http://127.0.0.1:8000/items/foo?q=somequery`) for `GET` requests.
-    * As the `q` parameter is declared with `= None`, it is optional.
-    * Without the `None` it would be required (as is the body in the case with `PUT`).
-* For `PUT` requests to `/items/{item_id}`, Read the body as JSON:
-    * Check that it has a required attribute `name` that should be a `str`.
-    * Check that it has a required attribute `price` that has to be a `float`.
-    * Check that it has an optional attribute `is_offer`, that should be a `bool`, if present.
-    * All this would also work for deeply nested JSON objects.
-* Convert from and to JSON automatically.
-* Document everything with OpenAPI, that can be used by:
-    * Interactive documentation systems.
-    * Automatic client code generation systems, for many languages.
-* Provide 2 interactive documentation web interfaces directly.
-
----
-
-We just scratched the surface, but you already get the idea of how it all works.
-
-Try changing the line with:
-
-```Python
-    return {"item_name": item.name, "item_id": item_id}
-```
-
-...from:
-
-```Python
-        ... "item_name": item.name ...
-```
-
-...to:
-
-```Python
-        ... "item_price": item.price ...
-```
-
-...and see how your editor will auto-complete the attributes and know their types:
-
-![editor support](https://squall.mtag.dev/img/vscode-completion.png)
-
-For a more complete example including more features, see the <a href="https://squall.mtag.dev/tutorial/">Tutorial - User Guide</a>.
-
-**Spoiler alert**: the tutorial - user guide includes:
-
-* Declaration of **parameters** from other different places as: **headers**, **cookies**, **form fields** and **files**.
-* How to set **validation constraints** as `maximum_length` or `regex`.
-* A very powerful and easy to use **<abbr title="also known as components, resources, providers, services, injectables">Dependency Injection</abbr>** system.
-* Security and authentication, including support for **OAuth2** with **JWT tokens** and **HTTP Basic** auth.
-* More advanced (but equally easy) techniques for declaring **deeply nested JSON models** (thanks to Pydantic).
-* **GraphQL** integration with <a href="https://strawberry.rocks" class="external-link" target="_blank">Strawberry</a> and other libraries.
-* Many extra features (thanks to Starlette) as:
-    * **WebSockets**
-    * extremely easy tests based on `requests` and `pytest`
-    * **CORS**
-    * **Cookie Sessions**
-    * ...and more.
-
-## Performance
-
-Independent TechEmpower benchmarks show **Squall** applications running under Uvicorn as <a href="https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7" class="external-link" target="_blank">one of the fastest Python frameworks available</a>, only below Starlette and Uvicorn themselves (used internally by Squall). (*)
-
-To understand more about it, see the section <a href="https://squall.mtag.dev/benchmarks/" class="internal-link" target="_blank">Benchmarks</a>.
