rewrote adaptive view stuff so we can use it on all types of views
(model-based, multi timestep, multi-mesh)

- deprecated "Complex Volume"

- moved some mesh creation utility routines in GModel::
- new MElementFactory
- fixed bad bg mesh index

untabify

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)

- clean up GModel API (xxByTag -> getXx, numXx -> getNumXxes, ...)

bug fix: even when a For/EndFor loop was not entered, we still increased
ImbricatedLoop. This could lead to undefined behaviour with nested loops

Smoother Surface{list} = numsteps;

make sure we define  YY_NO_UNISTD_H on wind32

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)

rename transf params & remove unused ones in old structs

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

added adaptive view options in the view's option db

removed global THEM

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

reinterfaced adaptive views with new post-pro

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 ***

allow Function Field(1)="expression"; (without extra empty list at the end)

added simple boundary operator in parser

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

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

Bezier curves are broken

small cleanups for 2.0.8
