//       Class : IndexRemapper
// Description : This class manages a mapping of integers to integers.
//               It's used in this package to resequence some or all
//               of the index numbers in the database to a different
//               sequence.
//
//               This class is just a wrapper around STL map.  The
//               only reason it exists is because Microsoft can't
//               export STL map outside of the DLL.
