--- Introduction ---
A cusp of a plane parametric curve
is a singular point for a value of ,
characterized by the simultaneous conditions
In this exercise, your goal is either to find a cusp in a
given parametric curve, or to determine the parametric curve
having a given cusp.
This exercise accepts several configuration parameters
which determine the aspect and the level of difficulty of
the problem asked.
