// $Log: test_point.cpp,v $
// Revision 1.4  2018/09/10 19:37:37  jlang
// Simplified point2d
//
// Revision 1.3  2017/09/13 16:09:27  jlang
// Wrapped point array in std::array. Removed use of pointers.
//
// Revision 1.2  2014/10/22 20:33:26  jlang
// changes for lecture
//
// Revision 1.1  2011/09/27 17:22:21  jlang
// Added bounding shape example
//
// Revision 1.1  2010/09/29 14:28:59  jlang
// Separate files for line_segment and point2d. Added test_point and make label test
