/** @defgroup EquationPolicy EquationPolicy
 *  @brief policies to specify how some primitives are modeled and implemented.
 *  @author Bram de Greve
 *  @date 2003
 *
 *  Some primitives, like 3D planes and 2D lines, you can model in one that more way.
 *  Typically, you can use the cartesian equation or a parametric equation.  You can
 *  use these policies to select one.  A third model combines both the cartesian and
 *  the parametric equation.
 *
 *  @note These polices are only place holders, selectors.  It means they are empty
 *        classes, and will select the real model when used.
 *
 *
 *  The content of the policies are rather implementation details, clients shouldn't
 *  worry about it.
