Stretchy limbs tutorial

To create the stretchy limbs I ended up using a tutorial from youtube which for the most part is quite easy to follow. It basically involves using three utility nodes : distance, condition and multiply/divide; which are then hooked into the joints and each other.

I was also given a tutorial by Dan on how to create stretchy limbs which involved using the expression editor. I started off with that method but ran into some problems, which I discussed with Clym. He then recommended me the tutorial on youtube which I had much less hassle with. I personally prefer using the utility nodes over the expression editor as I find it easier now.
