stretchy limbs redux

• seems as if it's important to have a master global scale in the baseCtrl.
• everything should be parented under the baseCtrl..
• 1/masterGlobalScale should be applied to the bendy chain joints.
• use of distance nodes to spread the chain joints is definitely the way to go in conjunction with translateX
• the root of the chain joint's immediate child should sit right on top of itself, for the bending to work
• use rotation of bendy joints to create bending
• IKctrl should be a shape of sorts, parented under baseCtrl. It should hold a locator for distance purposes and also the IK itself.
