Added fall back to uniform distribution of high-order nodes in parametric space if computation of equidistant distribution in physical space fails on model edges

geometry. It introduces subtle bugs when reading high-order post-processing views.

IMHO we should have an explicit command to do this, and not modify the mesh without
warning just by reading a file

use same tolerance in mesh extrusion as in geometry ; if this tol is too large, we should introduce another option

Replaced MVertexPositionSet with MVertexRTree ; use MVertexRTree in all extrusion algorithms instead of the (incorrect) std::set<MVertex, MVertexLessThanLexicographic>

Added "normalized corner Jacobian" quality measure for triangles and quads (not yet used nor tested)

Test of metric as a shape measure. It uses the slot Rho instead of adding a new slot, define METRICSHAPEMEASURE in GmshDefines.h to activate !

Removed lots of warning introduced with my last commit, cleaned up a bit duplicateBoundaries, and introduced support for 2D for DuplicateBoundaries.

More cleanup is going to follow soon, especially in the modified part of commandline.
