Auto-rig IK Limb Python Script

Overview:
The tech art team in the studio requires an autorigging tool for Maya that automates the process of creating IK limbs for robotic NPCs.

They've given you a file with an example NPC (see Mech_Spider.mb file) for testing.

A python script is needed with the following functionality:

• Ability to create a modular IK arm rig
• The user must be able to define the position and orientation of the module components (i.e. build the rig on top of an existing model)
• The user must NEVER have direct access to the joints.
• All components must be named with a consistent naming system.
• There must be a nicely designed UI for the tool.
