MooseX::Role::Parameterized::Parameters - base class for parameters

This is the base class for parameter objects. Currently empty, but I reserve the right to add things here.

Each parameterizable role gets their own anonymous subclass of this; parameter in MooseX::Role::Parameterized actually operates on these anonymous subclasses.

Each parameterized role gets their own instance of the anonymous subclass (owned by the parameterizable role).
