/**
 *  PURPOSE:
 *
 *  The label manager class is used to lookup label:value pairs
 *  stored in a text file. The constructor reads in the file whose
 *  name is passed to it and sorts the non-empty, non-commentary
 *  lines (commentary lines have a '#' as the first non-white
 *  character in a line) in ascending order to make binary searching
 *  possible. The binary search is performed by the lookup member
 *  function.
 *
 *  COMMENTS:  None
