Detailed Description

This class contains a collection of static functions for reading and writing simple types, in network byte order (MSB first).

It also contains functions to read and write strings. It also contains template functions to read and write STL deques, lists, vectors, maps, multimaps, sets and multisets. If you have an older version of gcc, there are functions for hash_maps and hash_sets. For gcc-4.2 and later, there are functions for tuple, unordered_map and unordered_set. We use our member functions to handle reading and writing simple types in the containers, and template functions to handle reading and writing other class types. For a user-defined class, the class must implement the Readable and Writable interfaces, since our template functions simply call out to them. Since templates are static polymorphism, you don't need to inherit from Readable and Writable, but you must implement the interfaces.
