Wrote NumberedPitch material package test.

The test is housed in the scoremanager/test/autoedit directory.

The test is a fairly powerful template.

The test ensures that composers can:

    * create a dedicated material package that defines a single NumberedPitch
    * autoedit the NumberedPitch
    * write the NumberedPitch to an output module

MODEL: It's conceivable that this basic pattern should be applied (eventually)
to all the custom classes in the API.
