All source uploaded

Ok, I finally got all the code committed to the repository and did an initial pass over the code to get all source files to compile, although it doesn't yet link. The work remaining to get code linking is to replace the pswraps (draw.psw) with efficiently coded drawing functions using AppKit drawing routines. To get the app fully running, there are several classes that need conversion from older PSops functions to NSBezierPath routines.
