adaptive_cloth: AdaptiveMesh: aspect ratio test when collapsing edge

Test to see if the faces generated when collapsing the edge will not
meet the aspect ratio criterion.

There is a lot more information about which algorithm is used for
calculating the aspect ratio in the code comments. A gist of it would
be that there many different ways to calculate the aspect ratio of a
triangle and each provides a different end result suitable for
different needs. This makes it hard to select the right algorithm.
