 /* cirTree chromosome id r tree.  Part of a system to index chromosome ranges - things of
  * form chrN:start-end.  Generally you'll be using the crTree module - which
  * makes use of this module and the bPlusTree module - rather than this module directly.
  * This module works with chromosomes mapped to small integers rather than chromosomes
  * as strings, saving space and speeding things up in the process, but requiring the
  * separate bPlusTree to map the names to IDs. 
  *   This module implements a one dimensional R-tree index treating the chromosome ID
  * as the most significant part of a two-part key, and the base position as the least 
  * significant part of the key. */
