[Kimchi-devel] [PATCH 04/22] Create a model to join all model resources implementation

[Aline Manera]

From: Aline Manera <alinefm at br.ibm.com>

That way we don't need to change tests and controller in order to use
the separated model implementations
All models will be automatically loaded into Model() which will contain
all methods needed by controller.
