Setting up flow for resolvers.

Repo structure classes should be responsible for pulling versioned files.
Ex. /forge/1.14/ -> get the latest file (or only allow one file).
The resolver then gets that file to work with in order to resolve the forge
module, pull its libs, and attach them as submodules.
