Module::Starter plugin to add new modules into existing distributions

 Module::Starter::Smart is a simple helper plugin for Module::Starter. It
 overrides the create_distro, create_modules, and create_t subroutines
 defined in whichever engine plugin in use (say, Module::Starter::Simple).
 .
 When invoked with an existing distribution, the plugin may bypass the
 create_basedir subroutine, pull in a list of existing modules as well as
 test files, create new modules, and recreate the manifest file accordingly.
