Implement extraction of regular Functions for parts of CCFEMFunction
Some work on CCFEM assembler
Add new class MultiMesh and move mesh related functionality
from CCFEMFunctionSpace to new class.
Rename CCFEMFoo --> MultiMeshFoo
Extract common multimesh for function spaces
Assembly over uncut cells
Add more convenient interface for computing quadrature rule for a cell
Bug fixes for computation of quadrature rules on cut cells
Partial implementation of assembly over cut cells
1st and 2nd order quadrature for simplices
Removed 3d point in 2d test
merged logg/topic-multimesh
added missing cmakelist
finished SimplexQuadrature, need to be tested
added MultiMesh to dolfin_mesh.h
Testing MultiMesh functionality
SimplexQuadrature testing
First test of MultiMesh triangle ok
MultiMesh unit test with two meshes ok
Testing collidision of three meshes
