Better mesh size control in triangle

Discussed in #257

Hi, I find that it is easier to control the mesh size in triangle by changing the max/min angle (in pre.py):

generate mesh

if coarse:
mesh = triangle.triangulate(tri, "pAo2")
else:
mesh = triangle.triangulate(tri, "pq30Aao2")

I could add this functionality if you wish.

I think this would really help with some of the segmentation fault issues #284 that I find will occur sometimes on thin cross sections.

Would there be any advantages to trying a different meshing library?

Hi @SoundsSerious, there is a new library cytriangle in development that looks promising - watch this space.

Yes that looks great, hopefully that would plug right into sectionproperties
