I'd like to easily be able to "fork" a feature on a site by running a drush command that will do the following:
Prompt for a module name if not provided as an argument. Should the module be validated to be enabled currently? It doesn't make much sense to fork a feature that hasn't been enabled yet.
Performs a recursive copy of the feature module directory to the modules/custom directory (can be overridden by --destination option).
Should probably delete the config/install and config/optional directories? Or should we just keep them?
