configure... Parameter definitions for "huygens"

The configure button allows one to reset several parameters in the simulation. Remember: If the number is still red, you need to hit Enter for the program to know the new number! If the parameters change while the Configure window is open, the window will not reflect the new numbers unless you hit the ``Revert'' button in the top middle. This mostly happens when one loads presets.
