Initial plan of attack

My plan of attack to get Cello out of the water is to port the file operations first. The first goal is to have something running on the Mac that can read a file (sample files generated from the Windows version) and then to be able to create the results (also a file). After that I can look at the visual representation of the file (getting it all to draw), the UI and all of the rest of it.

The program is written almost entirely in C++, so I figured that my start would be to map the file operations (etc.) to Core Foundation. Looking at the code, and from the brief tour of it from one of the Windows engineers Cello reads and writes compressed files. It uses a library called jcalg1 which is written in assembler. So the first dirty hands will be getting it to assemble in XCode.
