I/O issues

I've been doing a lot of work learning how boost::thread works and have started changing things around to allow for threading in general.  Unfortunately, in order to read data in anything resembling parallel, I need to change how files are opened entirely, which is posing a slight problem.  Currently I have separated the parts that can be executed in parallel from the normal encode and decode functions and started the process of changing how all file I/O is handled.
