/******************************* Classes ********************************
This header file declares various classes for interpreting and converting
different types of object files. These classes are all derived from the
container class CFileBuffer, declared in containers.h.
See containers.h for an explanation of the container classes and the
operators >> and << which can transfer a data buffer from an object of one
class to an object of another class.
