RobotModel defines the interface to a kinematics/dynamics functions. Implementations of this class will be used in conjunction with TrajectoryPt objects to determine forward and inverse kinematics.
All methods in this interface class assume a *FIXED* TOOL & WOBJ frame (see TrajectoryPt for frame definitions). The methods for setting/getting these frames are not defined by this class. Implementations of this interface should provide these either by construction or getter/setter methods.
