Detailed Description

Shared memory wrapper class.

This class enables separate processes to access the same peice of memory. A full discussion of the problems of pre-emptively multi-tasked processes accessing the same memory is beyond the scope of this document but suffice to say you need to know what your doing.

Initially all the bytes of the memory block are initialized to 0.
