ModelFactory works with prepared origin where possible.
Added test for 'computed' property.
[DEV]: It is now possible to work with model descriptions with the `namespace` and `serializable` properties to be optional.
[DOC]: Updated ReadMe to describe the new functionality.
[DEV]: Updated Package Information.
[DEV]: Removed costly `if()` clause for `serializable` and `namespace` properties of the model-description and instead remove them from the `keys` Array before each value is processed.
[DEV]: Renamed `model-factory` to `molder` to use constant names throughout the project.
[DOC]: Updated ReadMe to show some simple use cases of the JSON-Molder project
[DEV]: Upgraded the Molder so that it's also possible to desolate/reduce a "rich" model object according to the `serializable` property of the model-description, so that it's ready to be sent to the backend.

+ Added tests.
+ Added documentation @ ReadMe.
