* removed unused stuff (more to come)
* moved remaining into Common

  did in high
* added mesh generation error log summary
* removed Parallel subdir (this is now handled by the message class)
* removed Box subdir and consolidated batch processing in a single
  routine
* made List_T into a class
* reduced dependencies in Pview*.h so we can eventually add the post-pro
  interface to the public API

re-fix Field.h API dependency

fix shift/conflict reduce in parser introduced by Field stuff

api cleanup: use ByTag consistently (emphasises slowness of lookup)

Smoother Surface{list} = numsteps;

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 parser to work with new flex and bison (1.28 -> 2.3)

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 ***

added simple boundary operator in parser

add bit of code to intersect curves with a surface (allows to do "poor man's"
trimmed patches ;-)

small cleanups for 2.0.8

tCircle and tCoherence were removed from the lexer? WTF?

background mesh. I've still to write some fields sub-class, but backward
compatibility should be ok now.

----------------------------------------------------------------------

- 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

corrected some bugs in 2d mesher & occ interface

- save physicals labels when saving unrolled geometries
- fixed crash in unrolled geo save (discrete points)
- Delete Physicals now also deletes the physicals in GModel
- removed unused rules and terminals in parser
- put at least one mid-point when meshing non-straight lines
  in OCC: this fixes most of the trivial 2d meshing problems

removed most unused, untested or non-working stuff in old CAD code

new option to compute char lengths from curvature + removed most unused mesh options

curvature control is ok
divide and conquer algo has been cleaned up

more infrastructure for projection face gui

minimize the number of files that include GmshVersion.h: it's annoying to
recompiletoo many files just because the version string changes

"pure windows" version (without cygwin) is almost there: the solver
interface now works quite nicely using native Windodiows sockets and
the timers work too. There are still some bugs with binary files and
user-created functions in the parser.

removed the STEP parser: it's unusable, it makes the parser bigger,
and it introduces conflicts in the syntax.
