Updates!

Finally everything seems to be working - ironed out a bug which meant that the fracture didn't work in an extreme case. This looks to be fixed now. Also fixed some cases where the node didn't get duplicated because of the algorithm not working for cases where there is a boundary edge, a non-boundary edge and a cohesive edge on a face.

Reading is starting on the MPI framework and test programs will be written to see how it works.

CVS was updated today!
