//Control Box Setup utility for skeletons

//Description:
//  Recursively travels down a skeleton and creates a control box for each joint, parent costrainging the joint to the control box.

// Expand the Inital Bone selection to the whole sub-hierarchy
// and load the selection into $ccName string Array.

// Get the size of $ahName to determine how many times to run the loop
// Clear the Selection

	int $ahSize = size($ahName);
	select -cl;
	
// For Loop that Creates the Controller Box, moves it to the correct location and then 
// Parent Constrains the bone to it.
