MEL script IKFK Matching- WIP

I am writing a mel script that matches an IK skeleton to an FK skeleton and vice versa.
It works well and I am currently working on making it even better and then work on
making a UI so that the script can be applied to any character.

The script contains 3 parts now. The first part creates an IK set up.
The 2nd part matches an IK to FK and the third part is matching the FK
set up to the IK one.

I have included a video demonstration of the mel script
