bulletproof FindCurve/Surface + uniformize error messages

"Length -> Characteristic length" button label

removed SELECT test for mesh nodes: we don't use it

upgraded Triangle to version 1.5

- set OLDCINCLUDE flag for netgen on sgi
- use FLAGS in Netgen/Makefile

added sanity check for number of nodes per element

iostream.h -> iostream

make depend + update docs

don't optimize netgen meshes by default + use Msg(FATAL) when something bad happens

nicer physicals

update docs

forgot this one

added optimization hooks in the interface (GUI + comamnd line)

mesh optimization polish (redirect netgen messages to the GUI, etc.)

really simplex cube example

added "Optimize 3D" button in the GUI

We can now use Netgen's optimization pass on our own Delaunay meshes. It seems
to work pretty well on small examples, but it definitely requires more
testing :-)

a version of piece.geo with correct surface orientations so that
it works with netgen

- added small routine to orient all the surfaces in a Surface Loop
  consistently

- fixed orientation of lines/surfaces in holes, *IF* we suppose that
  holes are defined consistently with exterior boundaries (warning:
  there is currently *NO* check for this in the code)

more fixes for netgen

Added hooks to optimize our meshes using netgen (in particular: the "special"
volume 99999 is now cleaned up after use and all the elements/vertices are
transfered back into the original volumes)

As a bonus, this finally allowed me to remove the ugly hacks in the volume
mesh drawing routines...

optimize netgen mesh import (much much faster now for large meshes)

- revert the OPTIM change on 3D_Mesh.o
- fix bustage for --disable-netgen

keep netgen in make source

refactor the netgen code in a dedicated class

Merged Netgen 4.3.1: a Delaunay/Frontal 2D/3D mesh generator.

Thanks a lot to Nicolas Tardieu for this!

Store the surface orientations (from surface loops) in the volume: we need
this for Netgen.

mention explicitly if a plugin only works for simplices

Generalized Plugin(Triangulate) to handle vector and tensor views

Removed the orientation hacks completely. Should be pretty clean now.

set default RecombineAngle = 75

- %.1g -> %g to display bounding boxes
- update credits

Replaced my orientation hack with a rigorous algorithm... Seems to
work nicely (and is general).

Apply the surface re-orientation hack to quadrangles (and to extruded
meshes!)
