 /* rangeTree - This module is a way of keeping track of
  * non-overlapping ranges (half-open intervals). It is
  * based on the self-balancing rbTree code.  Use it in
  * place of a bitmap when the total number of ranges
  * is significantly smaller than the number of bits would
  * be. 
  * Beware the several static/global variables which can be
  * changed by various function calls. */
