Detailed Description

Generic file stream class based on STDIO.

CATStreamFile provides a basic file stream interface. It does NOT currently support locking (non-shared) modes, and will assert or return an error if you try to use them.

File sharing is a platform dependant issue. Create a platform dependant class inherited from CATStream if you need to control it. Alternatively, implement lock files or named semaphores in this class. I don't need it yet.
