is now "delaunized" using swaps using a "fast" algorithm

rename transf params & remove unused ones in old structs

fix nasty memory bug

	-) A bug has been corrected in the MeshAdapt Procedure
	-) The 2D Delaunay is now Anisotropic
	-) 3D Sliver removal procedure has been improved
	-) Curvilinear mesh generation has been slightly improved,
	   even if it is still far from done

fix crash in collapseEdgePass

prelim support for native file chooser from erco

fix infinite loop

make depend

Removed the "search around point" strategy when we provide a background mesh.

(Now that we can have several fields, it's much better to specify another default
field for when a search fails.)

Detect when we have zero lc and fix it (+ send an error message)

OCCFace::containsPoint() did not correctly take orientation of edge loop
into account (fixes bug reported by Jacques Kools about cross in OCC plane
faces not drawn)

commited. It allows to remove self intersecting meshes in
the 2d mesh generation process. It only applies now to
gmsh native CADs. Those limitations will quicky go away

- fixed remeshing of boundary layers when geo entities are constructed
using bnd layer points (no need to reload the file from scratch anymore
to avoid accumulating the transformations)

- patch load_gmsh.m for .msh version 2 (patch from Raoul)

- new load_gmsh2.m from the mailing list

add experimental support for automatic on-the-fly boundary computation
in vertex arrays

new Mesh.RefineSteps to control how many refinement steps we perform in
2D MeshAdapt-based algorithms

rewrote vertex array code for meshes in the same way we do it now for
post-processing (much simpler, pretty much same speed, and takes a bit
less memory)

moving to new post-processing database
