set up basic structure
implemented most of the equivalence classes for resulting elements of collapsed nodes
generalised quad/tet creation
renamed coplanar() to isCoplanar()
finished possible deformations for all element types
added subdivision of elements if they are not planar
added tests and cleaned up main
added method for returning number of collapsable nodes
replaced a few for loops with iterators
added necessary includes
