Detailed Description

Binary buffer input class.

This class is used to read data from a binary buffer. The data in the file is assumed to be big-endian. If the host nachine is little-endian, the data is byte-swapped. All nodes end up with the same data

The read methods are also wrapped by externally defined functions and >> operators,
