* The Module class template defines a standard internal interface between IPA
* modules and libipa.
*
* While IPA modules are platform-specific, many of their internal functions are
* conceptually similar, even if they take different types of platform-specifc
* parameters. For instance, IPA modules could share code that instantiates,
* initializes and run algorithms if it wasn't for the fact that the the format
* of ISP parameters or statistics passed to the related functions is
* device-dependent.
*
* To enable a shared implementation of those common tasks in libipa, the Module
* class template defines a standard internal interface between IPA modules and
* libipa. The template parameters specify the types of module-dependent data.
* IPA modules shall create a specialization of the Module class template in
* their namespace, and use it to specialize other classes of libipa, such as
* the Algorithm class.
