Set up first draft for the morphing section

Also added a small part for in the Approach and Design

@droidstealth/developers  The parts that are there are ready for review. I'll add the final part tomorrow.
I agree that especially the fourth paragraph could use some rewriting because it's rather vague, but I don't think the entire intro should be described as vague. It is instead the reasoning behind our approach, and as far as I remember, quite close to our thought process at the time. Explaining readers how we arrived at our implementation is something I consider if immeasurable value, since we have little hard data to back up our current approach, besides those discussions with Hadi.
