+/**
+ *  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
