#generate_directory ⇒ Object

nodoc: This hardcodes the monorail directory structure. Obviously not satisfactory. We’ll need some softer way of doing this eventually. WE ARE ASSUMING the directory structure of the gem. We expect to be in directory lib/monorail, and we look to copy the directory found at ../../skel relative to ourself.
