set_rootcommand also generates four helpers.
Eucalypt.rootsimply returns the full application root directory path as a string.
Eucalypt.pathallows for the construction of absolute paths relative to the application root directory.
Eucalypt.globallows for the globbing of files relative to the application root directory. The method works in the same way as
Dir.glob, and also accepts a block that allows you to operate on the globbed files.
Eucalypt.requireallows for the requiring of multiple files relative to the application root directory. Note that it is not possible to specify the order in which files are required.
Kernel's require method, files must include their extensions.
