// Change Log
//
// 1 - Mark Fischler Feb 6, 2008
//	Internals for implementation of glob-style wildcard selection
//	In particular, !xyz* requires the vector nonveto_bits_
//	nonveto_bits_ is designed to also accomodate an AND of triggers
//      selection criterion, if that is wanted at some future date.
