- 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

bidir db: phase 3 -- move all the old geo stuff into Geo/
