POC implementation of multiple routes

[dantleech]

This PR is primiminary attempt at supporting the generation of multiple routes (from schemas) for a single class.

The configuration would look as follows:

stdClass:
    extend: foo
    routes:
        route_one:
            uri_schema: /route/to/{foo]
            token_providers:
                foo: [ bar ]
        route_two:
            uri_schema: /path/to/{foo]
            token_providers:
                foo: [ bar ]

While also supporting the current format:

stdClass:
    extend: foo
    uri_schema: /route/to/{foo]
    token_providers:
        foo: [ bar ]

Note that this is far from being in a working state.
