  48  * streamlined headers inclusion

  50  * Revision 1.4  2006/02/19 19:46:49  strk
  51  * Packages <-> namespaces mapping for most GEOS internal code (uncomplete, but working). Dir-level libs for index/ subdirs.

  53  * Revision 1.3  2005/11/21 16:03:20  strk
  54  *
  55  * Coordinate interface change:
  56  *         Removed setCoordinate call, use assignment operator
  57  *         instead. Provided a compile-time switch to
  58  *         make copy ctor and assignment operators non-inline
  59  *         to allow for more accurate profiling.
  60  *
  61  * Coordinate copies removal:
  62  *         NodeFactory::createNode() takes now a Coordinate reference
  63  *         rather then real value. This brings coordinate copies
  64  *         in the testLeaksBig.xml test from 654818 to 645991
  65  *         (tested in 2.1 branch). In the head branch Coordinate
  66  *         copies are 222198.
  67  *         Removed useless coordinate copies in ConvexHull
  68  *         operations
  69  *
  70  * STL containers heap allocations reduction:
  71  *         Converted many containers element from
  72  *         pointers to real objects.
  73  *         Made some use of .reserve() or size
  74  *         initialization when final container size is known
  75  *         in advance.
  76  *
  77  * Stateless classes allocations reduction:
  78  *         Provided ::instance() function for
  79  *         NodeFactories, to avoid allocating
  80  *         more then one (they are all
  81  *         stateless).
  82  *
  83  * HCoordinate improvements:
  84  *         Changed HCoordinate constructor by HCoordinates
  85  *         take reference rather then real objects.
  86  *         Changed HCoordinate::intersection to avoid
  87  *         a new allocation but rather return into a provided
  88  *         storage. LineIntersector changed to reflect
  89  *         the above change.
  90  *
  91  * Revision 1.2  2004/07/02 13:28:26  strk
  92  * Fixed all #include lines to reflect headers layout change.
  93  * Added client application build tips in README.
  94  *
  95  * Revision 1.1  2004/03/19 09:48:45  ybychkov
  96  * "geomgraph" and "geomgraph/indexl" upgraded to JTS 1.4
  97  *
  98  * Revision 1.7  2003/11/07 01:23:42  pramsey
  99  * Add standard CVS headers licence notices and copyrights to all cpp and h
 100  * files.
