rewrote vertex array code for meshes in the same way we do it now for
post-processing (much simpler, pretty much same speed, and takes a bit
less memory)

- polished mesh option strings in gui
- merged modified extrusion patch from <mi.benham@free.fr>

cleanup

1D transfinite mesh algo was completely broken.

sigh.

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

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

new boundary layer mesh generator

refactored smooth value/smooth normal code into single SmoothData.* file

enhancement of gmsh Surfaces

JFR

- fixed missing return value in OCCVertex::reparamOnFace

- added code to highlight orphan entities (dave's idea)

- added gui for incomplete second order elements

- removed ugly static variables in 1d algo

- made sure we remove all 2d order vertices before generating new ones

destroy meshRep in deMeshGEdge

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

extrude edge+face (only "recombined" for now; we'll implement subdivision
into simplices "globally" later)

more cleanups
