CompassBiped > Set

Added a "set" method to change any and many parameters of a CompassBiped
object. This will be helpful for quickly setting up different simulation
conditions.
Simulation single file

Added a "set" method for the Terrain class + caught minor bugs.

Working on the required parts of a Simulation object as a whole before
taking it apart into smaller files.
Right now the simulation is running including the compass biped events
(albeit not really since nothing extends the leg after it's retracted).
Controller

Worked on adding pulses to the new controller pbject
