The DataSource module provides access to any Fins.Model.ModelDataContext objects defined
by the application's configuration file. The default model definition is always available
as Fins.DataSource._default, and Fins.Model.find operates on the default model definition.
Any other models defined for an application can be accessed via Fins.DataSource.id where
id is the value of the id configuration parameter in the model's configuration section.
