<void>ikChain <node>startJoint <node>endJoint <boolean>createEndEffector
Creates an IK chain from the given start joint to the given end joint node. If createEndEffect is true, an end effector will be created.
Calling this method on the master controller causes all slave controllers in the chain to be replaced with default transform controllers (PRS). This method will support undo if it is enabled but will not turn undo on. This method does not cause viewports to be redrawn.
HD IK controller chains can be assigned to existing hierarchies
