Detailed Description

This class provides wrappers around entities and components which are more convenient and straight-forward to use than dealing with the EntityComponentManager directly. All the functions provided here are meant to be used with a model entity.

For example, given a model's entity, to find the value of its name component, one could use the entity-component manager (ecm) directly as follows:

std::string name = ecm.Component<components::Name>(entity)->Data();

Using this class however, the same information can be obtained with a simpler function call:

Model model(entity); std::string name = model.Name(ecm);

Todo:
(louise) Store the ecm instead of passing it at every API call.
