00032 Revision_history:
00033 
00034 2004/05/22: Etienne Lachance
00035    -Added class Trajectory_Select.
00036 
00037 2004/07/01: Etienne Lachance
00038    -Added doxygen documentation.
00039 
00040 2004/07/01: Ethan Tira-Thompson
00041     -Added support for newmat's use_namespace #define, using ROBOOP namespace
00042 
00043 2005/11/06: Etienne Lachance
00044     - No need to provide a copy constructor and the assignment operator 
00045       (operator=) for Spl_Quaternion, Spl_Cubic and Spl_path classes. Instead we 
00046       use the one provide by the compiler.
