Moved the build system over to CMake. This build system right now
replicates the same functionality as our bash scripts from earlier. Will
need a lot of refactoring to be more complete, but for now we are fully
on CMake.
Changed location of the /build directory to be in the root to make for
easier cleaning of project. Added in a clean-all.sh script as well to
clean everything.
Clean Script
Added in a way to clean the build environment as well.
