/*!
INITIAL VALUE
This object has no state.
WHAT THIS OBJECT REPRESENTS
This object simply provides a mechanism to convert data from a
host machine's own byte ordering to big or little endian and to
also do the reverse.
It also provides a pair of functions to convert to/from network byte
order where network byte order is big endian byte order. This pair of
functions does the exact same thing as the host_to_big() and big_to_host()
functions and is provided simply so that client code can use the most
self documenting name appropriate.
Also note that this object is capable of correctly flipping the contents
of arrays when the arrays are declared on the stack. e.g. You can
say things like:
int array[10];
bo.host_to_network(array);
