Changed the storage of offsets from bytes to bits to better handle bitfields. Added code to track classes that are defined within other classes and are private/protected. These classes cannot be used in templates because our io_src code declares variables outside of the class that would try and use these private/protected variables. When a template is found to use a private/protected class it is skipped. refs #218
