More Progress

Ah, good progress. I finished writing the stream and CD classes, including documentation. This puts the sound module at approximately 95% completion, with just a few unimportant initialization and shutdown functions to worry about.
School starts in two days, so beta release might be delayed a while, but probably within the next week.
I've already got a working model of the input module (which is next on the list), that shouldn't take very long.
