Provides base interface for Databinding the controls in this assembly. Each
of the controls implements this interface to support the logic of the
inding and to allow the renderers to find bound controls on a Web form.

he key methods are BindData and UnbindData which handle binding data from
he datasource to the control and from the control back to the datasource.
hese methods simply call into the wwWebDataHelper class's relative methods
to perform the actual logic of databinding using Reflection.
