 * $Log$
 * Revision 1.19  2006/03/21 13:11:29  strk
 * opRelate.h header split
 *
 * Revision 1.18  2006/03/17 16:48:55  strk
 * LineIntersector and PointLocator made complete components of RelateComputer
 * (were statics const pointers before). Reduced inclusions from opRelate.h
 * and opValid.h, updated .cpp files to allow build.
 *
 * Revision 1.17  2006/02/19 19:46:50  strk
 * Packages <-> namespaces mapping for most GEOS internal code (uncomplete, but working). Dir-level libs for index/ subdirs.
