Interface for closed form inverse kinematics algorithms.
The ClosedFormIK interface provides an interface for calculating the inverse kinematics of a device. That is to calculate the solutions , such that .
By default it solves the problem beginning at the robot base and ending with the frame defined as the end of the devices, and which is accessible through the Device::getEnd() method.

Closedform IK solver for a device.
The device must be a serial device with 6 revolute joints described by DH parameters.
The IK solver is currently implemented in terms of PieperSolver. See the documentation of PieperSolver for the specific requirements for the DH parameters.
An exception is thrown if closedform IK for the device is not supported, except that all such cases are currently not discovered. You should check for yourself that the closedform IK for the device is correct.
