remove extra volume

add more step/stl benchmarks

general, but ProjectPointOnSurface for example would fail on plane
surfaces)

added General.MinX, General.MaxX, etc. so that we can easily get the
min/max of a model (useful e.g. to create a box around an imported
STEP model)

added example of mixed step/geo model

rewrote the interactive edge/face link finding routines in terms of GModel

(hence we can now create volumes from OCC faces in the GUI)

add tooltip for mesh quality (dave)

use the 3D Delaunay by default (if tetgen is available)

fix opti crash with Delaunay algo (forgot to classify new vertices in correct region!)

include the geometrical entities defined in this script (since we
import THEM into GModel *after* we've parsed the file)

orientation bug in extrusion

- make it easier to build universal binaries on Mac
- remove unused arg in transform functions (an prepare the terrain for periodic meshes)

better text in warning dialog when appending string to non-.geo file

polish

- print num vert+elm after each generation
- reork tutorial a bit

displays nowadays often have more than 1024 pixels

cleaned last gcc warnings

tagging gmsh_2_0_0

small things

- added warning dialog before attempting to append a scripting
command to a non-geometry file

- fixed mean plane computation for periodic curves

- added headers + ramn indent on Attractor files

enhancement of gmsh Surfaces

JFR

fix shift/reduce conflict in parser (had to slightly modify embedding syntax)

 more work to get universal libs and binaries on os x: use libtool
instead of ar

make depend

corrected some bugs in 2d mesher & occ interface
