* is designed to allow people to easily create ETableModels without having
* to create a new GType derived from ETableModel every time they need one.
*
* Instead, ETableSimpleModel uses a setup based in callback functions, every
* callback function signature mimics the signature of each ETableModel method
* and passes the extra @data pointer to each one of the method to provide them
* with any context they might want to use.
*
* Returns: An ETableSimpleModel object (which is also an ETableModel
* object).
