* New ENABLE_COMPRESSED_IO option to enable on-the-fly IO with gzipped files (patch from Alexis Salzman)
* New PrintParserSymbols() to print workspace (currently in option window, for debugging puroposes)

new -setstring and -setnumber command line options (to define parser variables without parsing, like in getdp)

Added temporary hack to force the Newton-Raphson algorithm used in GFace::XYZtoUV to enforce convergence in XYZ coordinates. Math should be checked for ruled surfaces obtained by extrusion, as some more fundamental problem seems to exists for points on the boundary of the CAD patches
