 == Data provider types ==
 
 The base data provider '''ITmfDataProvider''' interface is the interface each data provider type has to implement. The data provider factories create instances of such provider type. Tree data providers are of type '''ITmfTreeDataProvider''' extend the '''ITmfDataProvider''' interface and returns a tree, as a list of '''TmfTreeDataModel''', with a name, ID and parent ID. The ID is unique to a provider type and the parent ID indicates which element from the list is the entry's parent to rebuild the tree hierarchy from the list of models. Note such tree need to have limited size to not exceed the available memory.
