for example:
pax-create-module -a wrappers
will create a new module called wrappers, with groupId and version computed from the parent.
this command should also support creating a nested path, with a custom group and version:
pax-create-module -a market/stock/quote -g finance -v 2.0
will create a series of new modules, with the last pom having the custom groupId and version.
