// Some compilers require definitions of template methods to reside
// in a separate .cc file, and some require them to reside in the .hh
// file (this file).  The following construct allows us to control
// this from the makefile.
 
// 1. Implement your methods in HTRange.cc.
// 2. Exclude the HTRange.cc file from the list of compilations.
