use geom.tol in FinishUpBoundingBox

move random seed init in GenerateMesh

API cleanup: FVertex, FEdge, etc. -> fourierVertex, fourierEdge, etc.

make parser embeddable in code with other parser (yy->gmsh_yy)
more work on headers
fixed lots of gcc warnings

start reducing header pollution (removed Gmsh.h + cleaned up GModel & co)

fix memory bugs

constness fixes

removed global THEM

(once more step towards nicer integration of old GEO stuff)

- fix crash in Plugin(MakeSimplex)
- fix main bbox computation when one view has an empty bbox

fix crash in batch mode

moving to new post-processing database

                    *** WARNING ***

do not upgrade if you need plugins or adaptive views: these have not
been ported (yet) to the new database

                    *** WARNING ***

airplane work: more work to complete remaing features (read, combineSpace,
combineTime) in new post-pro

- removed static GMODEL (can now have multiple models)
- added infrastructure for new post-processor module

- better SplitFileName (e.g. to remove full path from
  \includegraphics{} in .tex files)

- better interactive positionning of projection surfaces

small cleanups for 2.0.8

- better tol in checkMeshCoherence()

add test version of fourier model

- preliminary work to interface more parser functions with general
  GEntities

- we can now export simple GModels as.geo files (points, straight line
  segments, plane surfaces, ruled surfaces and volumes are treated
  correctly; all non-straight-line curves are exported as splines; all
  non-plane/ruled surfaces are not exported)

- tentative fix for the unv export problem reported on the mailing
  list (fprintf() buggy on some machines??)

- new IO (both read and write) for structured grids using the NASA
  Plot3D format (for Olivier)

- boundary layer can now be generated by using a post-pro view for the
  normal field

- added more operations on lists in parser (FExpr * FExpr_Multi, etc.)

- new "hole carving" code to create extruded grids carved out around
  some surfaces (the resulting cavity can be filled with "grout" using
  the unstructured algos)

- check if bboxes of post-pro views are not == VAL_INF before adding
  them to the model bbox (bug report from Renaud Sizaire)

- fixed crash in LCM_xxx tensor drawing code when no tensor points are
  available. (This piece of code should be cleaned up further--no time
  for that now.)

- generalize Levelset plugins so that they work on point data sets

- using quads to draw 2nd order elements was a bad idea (they can be
non-plane, so the normals computed for lighting did not always look
nice). It's better to just split each quad into 2 triangles.

- import THEM in ParseString

removed gobal meshSize in GMODEL: for now use CTX.lc, which is correctly
updated when multiple files are merged

- new option Geometry.Tolerance (or -tol on the command line) to set the
tolerance for the old CAD engine, for OCC healing and for STL import

- removed more unused options

- bug fix: need to create temporary bounding box and compute CTX.lc
*during* parsing step until we fill the new db on the fly

(Some geo transforms in the parser use CTX.lc for tolerences. But
CTX.lc was always equal to 1 since we only do a SetBoundingBox on
GModel after parsing!)

- cleanup spline interpol (remove duplicate code)

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