+// CLASS DESCRIPTION (MArrayDataHandle)
+//
+//	An MArrayDataHandle is a smart pointer into a data block (MDataBlock) that 
+//  handles access to array data.  MArrayDataHandle supports attributes that
+//  can have an array of data.
+//
+//  The array indices do not have to be continuous.  The array can be sparse.
+//  Thus, an array could have four elements with the indicies 1, 6, 8, and 10.
