+   MD5SumValue - Storage for a MD5Sum
+   MD5Summation - MD5 Message Digest Algorithm.
+   
+   This is a C++ interface to a set of MD5Sum functions. The class can
+   store a MD5Sum in 16 bytes of memory.
+   
+   A MD5Sum is used to generate a (hopefully) unique 16 byte number for a
+   block of data. This can be used to gaurd against corruption of a file.
+   MD5 should not be used for tamper protection, use SHA or something more
+   secure.
+   
+   There are two classes because computing a MD5 is not a continual 
+   operation unless 64 byte blocks are used. Also the summation requires an
+   extra 18*4 bytes to operate.
