bug #4 fix generics templates (bendavies)

This PR was squashed before being merged into the main branch.

fix generics templates

This PR fixes the templates for `MicroMapperInterface` and `MapperInterface`.
regression tests have been added.

as an aside, is the `$toClass` param in `MapperInterface::populate(...)` redundant?
It seems we will only ever have concrete implementations here and will just new up a new class, which will match the class provided in the `AsMapper` attribute.
