Friction-damped mass-spring saccade controller.
FrictionSaccadeController acts like a mass (at saccade center) connected to the covert focus of attention through a spring of zero rest length, and sliding on a plane in the presence of friction.

Constructor.
| part | As this controller may be used either for the eye or for the head (as part of bigger controllers that include both eye and head), this should be either SaccadeBodyPartEye or SaccadeBodyPartHead and will determine which model options we use for our internal parameters (eye or head) |
