Should the Memory part be a standard part?

[andrew-wilkes]

I tested the software with a Memory part that was used in the Computer simulation. But this is specific to Nand2Tetris and should be built from other parts by the student. So I may remove this part from the Part library.

Also, I need to recall why I thought that I needed to add this part in the first place. Maybe it was because it needed to do something that was impossible otherwise?
