A model of a mimic joint. Mimic joints are typically unactuated joints that are constrained to follow the motion of another joint. The constraint is linear, i.e. joint_angle_constrained_joint = joint_angle_mimicked_joint*multiplier + offset
Specific implementation of kinematics using ROS service calls to communicate with external IK solvers. This version can be used with any robot. Supports non-chain kinematic groups
