Fixes #5

Some notes:

• Upon refactoring for this repo to manage multiple instances of Morpho, I came to a personal conclusion that it would be problematic to use ma3 as a submodule. This would necessarily conflict with ma2/mc, so I worked instead to keep the dependencies limited as much as possible by removing all unnecessary elements. So now this repo functions almost purely on interfaces and foundry cheats. All interfaces and libraries are refactored to be self contained within this repo.
