Renamed compound_only parameter to showCompound. Enable to fix issue with invisible discrete meshes.

Some steps to a better usability with compounds. Improvements in drawing of compounds: Edges of compounded surfaces in the CAD are hidden, only the collection of compounded surfaces is shown, the single surfaces are hidden. The draw command is called for the compound and then piped to the underlying surfaces. Can be controled with commandline parameter 'compound_only'. Further steps will follow in near future (high order meshes using compounds etc.).

bug removed in GFaceCompound.cpp (sorry for that, Tristan, my fault)

The delquad algo is now much more stable and nice

Two 3D meshers have been added. 

One is an embryo of the 3D delhex mesh which is an extension of delquad.

The other one is MMG, the mobile mesh generator of CECILE DOBRZYNSKI (Bordeaux I) and PASCAL FREY (PARIS VI). We are very happy that this new anisotropic 3D mesher is now available as an open source !!

cross field computataion ok in 2D
high order tools bugs fixed
wing-spline is now a correct geometry
meshing in two passes is now permitted (like in bamg)

- fixed MED node ordering
- polished 64 bit Cocoa Mac OS X FLTK version
- updated copyright

Add the option to prevent using metrics for high-order mesh generation (useful for some matched OCC models atm)

Adds an option to switch elementary and physical tags in loaded meshes, and fixes a bug with geo-mesh matching.

fixed newton in DG

* basic Abaqus INP mesh export
