Renamed the public functions in Memory to comply with standards
Merge branch 'master' of https://github.com/larsonp4620/CompArch1.git
Added Mux, Wire, Writable, Readable, and ALU...

ALU still needs to have its normal ALU functions written, but otherwise
is ready to go (readable/writable functions are set up)

Mux is basically just a wire with a control bit and multiple inputs. The
control bit chooses the input. We could replace all Wires with Muxes if
need be.

Finally, I need to fix Memory and Register still -- neither implements
Readable/Writable yet but I'll wait on that. Chem studying time!!!!!!1
