- removed ugly fix in transf mesh of tri surf
- use MFaceVertex params in boundary mesh if available
- cleanup intro chapter in docs

prepa invert_selection + remove some debug prints

more occ work

more occ work

start opencascade integration

start work on mesh>edit feature (delete elements, etc.)

- patch from gabriele bellussi
- added GUI hooks for new mesh editing/reparam stuff (for jacob)
- more work on fourieModel

- second order nodes on geometry by default
- better min/max range computation for cut planes
- more work on fourierModel

force orientation of mesh to match the orientation of the geometry

keep existing vertex numbers when reading meshes (when it makes sense)

fix missing SIGN in NR

make negative physical entities behave like they're supposed to

- setParameter in MVertex
- revert() for quad
- minor cleanups in I/O code
- start work on overlap mesh in fourierModel

finish BDF reader for 2nd order elements

- Use correct vertex ordering for second order simplices in UNV format
(thanks to Romuald Conty <conty@phimeca.com>)

- MLine2 -> MLine3

better fix

- start work on fourierModel
- add support for pyramids in BDF (it's not in the official spec I have
  here, but all the files I found on the web use CPYRAM)
