physical entities can now be defined using a string instead of a number (and
there is a new field $PhysicalNames in the .msh format to keep track of these
strings)

remove elliptic - same as Transfinite with Mesh.Smoothing > 1

- finished volume extrusion
- cleanup ExtrudeParam (plug memory leak + remove unused stuff)
- make netgen the default 3D algo for now (since it actually works)

make explicit regions in extrusions DEPRECATED

remove more attractor crap

cleanup

bidir db: phase 3 -- move all the old geo stuff into Geo/

bidi db: phase 2 -- continued

bidir db: phase 2 -- removed all (well, most of) the old data structures and
algorithms

bidir db: phase 1

fix crash when trying to draw a geom while the db is being built

occ mingw

support for CGNS IO

occ work

:i

start opencascade integration

more mesh edit work

new GModel::writeGEO (only implemented for gmshModel for now; goal is to be able
to implement this for other derived model types (like OCC) later, too)

better fix

fix crash when adding a geo entity while a mesh is displayed

- finished Nastran BDF implementation (read+write in all BDF formats:
  free field, small field & long field)
- improved UNV and Medit import
- added detection of bad vertex indices in all import routines
- fixed bug in 2nd order quad constructor

- changed UNV output to match MSH output w.r.t. physical groups
- new UNV file reader

Added support (both read and write) for the Nastran Bulk Data File
format (BDF).

This might need some adjustments depending on what the actual spec
is: I just reverse engineered some BDF files I found on the web :-)

refer to .mesh as MEDIT format, not INRIA format

- better computation of bounds for discrete entities
- added small widget for light position selection
- infrastructure for Fourier models

simplify TeX printing

- done rewriting second order algo

- small optimizations here and there to speed up the vertex array creation
  (we should get rid of List_Add & co)

reduce dependencies by putting the selection buffer stuff in its own file

Implemented new binary MSH file format (both read and write).

A 250Mb mesh file (6 million tetrahedra) is now read or written to disk in
less than 10 seconds (on my powerbook's slow hard drive).

added binary stl export

- rewrote selection code to use dynamic arrays, so that we should never
overflow the selection buffer again (even on huuuuge models)
- cleanup some leftovers "useing namespace std"

make sure to rest the model before doing a add_in_file in the old geo code
(since the parsed command could delete an entity!)
