[forge-dev] invoking project classes

[Lincoln Baxter, III]

We can work on prototyping this feature in Forge. This is within the forge
Vision, but needs to be done carefully. Maven has some tools for getting
information about a project's dependencies and deliverables. See the
MavenDependencyFacet and RepositoryLookup classes. The MavenSystemSession
class in RepositoryLookup has methods for reading a project POM. Perhaps we
could leverage those. Although, wouldn't this kind of Export better be
handled by the test framework itself, since it is already classloading
everything?
