00023 Revision_history:
00024 
00025 2004/07/01: Etienne Lachance
00026    -Added doxygen documentation.
00027 
00028 2004/07/01: Ethan Tira-Thompson
00029     -Added support for newmat's use_namespace #define, using ROBOOP namespace
00030     -Added dependance on utils.h because we need to get the use_namespace setting
00031 
00032 2004/07/13: Ethan Tira-Thompson
00033     -Added a select_real and add_real function for type indepence of Real
00034     -Added functions to test for sections and parameters existance
00035 
00036 2004/07/29: Etienne Lachance
00037    -Added clear function. Suggested by Sylvain Marleau.
00038 
00039 2004/08/10: Etienne Lachance
00040    -Removed select_real and add_real functions in order to make config.h/cpp 
00041     independent of ROBOOP.
00042    -Removed using ROBOOP namespace
00043 
00044 2004/08/14: Etienne Lachance
00045    -Merge all select_* and add_* functions into select() and add() functions.
00046 
00047 2006/02/04: Etienne Lachance
00048    -Member functions add and select are now in template form.
