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