Rake my current created routes

# What 

I wanted to know all the routes i created in my project and i did not want to go through all the controllers i created holding the routes. So i added a function to print out the routes. Its a small thing, i just found it very helpful and maybe something even better can be done here to make this information rake more detailed and useful. Maybe even prettier printing. 

# How

Your project should have this structure

    vendor/
    etc/
         -> app.php
     index.php
     rake.php
     .htaccess #to force all urls through index.php

example my .htaccess is

    Options -Indexes

    DirectoryIndex index.php

    RewriteEngine on
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond $1 !^(index\.php|assets)
    RewriteRule . index.php [L]

* Inside `etc/app.php` have all your code with routes e.t.c **except** for `$klein->dispatch();`
* Inside `index.php`, include require `/etc/app.php` and call `$klein->dispatch();`
* Inside `rake.php`, include require `/etc/app.php` and call `$klein->rakeRoutes();`
You can't run a `list()` operation on an object instance like this. I'm not sure how you've gotten this to work. Did you test this?
