  36  *
  37  * This is a basic binary search table that employs a copy-on-write data
  38  * storage mechanism. It can be used to contain a structure that has a key and
  39  * possibly some data. The key should be a member of the element class and
  40  * accessible with getKey(). A class containing the compare routine must be
  41  * supplied.
