00024 Revision_history:
00025 
00026 2004/07/13: Ethan Tira-Thompson
00027     -Added support for newmat's use_namespace #define, using ROBOOP namespace
00028 
00029 2005/06/10: Etienne Lachance
00030     -The desired joint acceleration was missing in the computed torque method.
00031 
00032 2005/11/06: Etienne Lachance
00033     - No need to provide a copy constructor and the assignment operator 
00034       (operator=) for Impedance, Resolved_acc, Computed_torque_method and
00035       Proportional_Derivative classes. Instead we use the one provide by the
00036       compiler.
