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

new PostProcessing.ForceNodeData to force saving NodeData datasets, even for potentially discontinuous list-type datasets

Fopen deals with non-ASCII filename paths on Windows.

- getfunctionspaces now returns a nodalBasis instead of polynomialBasis
- reversed order for saving elements in GModelIO_MSH - makes things simpler for subelements
- taking msh file version into account while exporting data files (PView ...)

start implementation of MSH3 format:

- refactored old MSH I/O into GModelIO_MSH2
- new MSH3 will be GModelIO_MSH

- fixed MED node ordering
- polished 64 bit Cocoa Mac OS X FLTK version
- updated copyright

Add FullDg formulation
Add Stress and InternalPoint (development)

- moved GUI to FlGui + added experimental QGui to test Qt

- fixed most MSVC and gcc compiler warnings

- converted some remaining tabs to whitespace (that's why the patch is
  so large; please try to remember to indent with 2 spaces and not
  tabs when you commit stuff to CVS)

- merged modified patch from Konstantinos Poulios to allow saving
  physical/partition as element tags in mesh formats that don't
  support them natively

- replaced old 2nd order views with new adaptive stuff (still missing
  some function spaces for quads/hexas)

moved all string options to std::string

- fix bb computation to avoid model jumping around when adding points in z=0 plane
- pass interpol matrices as ref

  did in high
* added mesh generation error log summary
* removed Parallel subdir (this is now handled by the message class)
* removed Box subdir and consolidated batch processing in a single
  routine
* made List_T into a class
* reduced dependencies in Pview*.h so we can eventually add the post-pro
  interface to the public API

  integer tags per step data
- ported Eigenvectors and StreamLines plugins to the new post-pro API

- deprecated "Complex Volume"
