I'm having trouble getting the CSG demos (in the dolfin-csg branch) to
compile. Any hints?

  sec ~/src/fenics/src/dolfin-csg/dorsal_build_dir 1$ make demo_csg
  Building CXX object
demo/undocumented/csg/cpp/CMakeFiles/demo_csg.dir/main.cpp.o
  demo/undocumented/csg/cpp/main.cpp: In function ‘int main()’:
  demo/undocumented/csg/cpp/main.cpp:35:3: error: ‘csg’ has not been declared
  [etc]

It looks like it's missing an include, and adding "#include
<dolfin/generation/CSGPrimitives2D.h>" helps a little. However:

  demo/undocumented/csg/cpp/main.cpp: In function ‘int main()’:
  demo/undocumented/csg/cpp/main.cpp:37:44: error: no match for
‘operator-’ in ‘c - r’
