smoothing 1D mesh is now (maybe) correct

Worked a lot oncurvilinear meshing : projection of point on surafces work, matching meshes andgeometry works better, added some test examples...

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

No commit message

started to create parallel topology in the mesh

- pretty print code

re-committing work from last two days after server crash:

- refactored old Geo code (new/delete)
- moved DrawPlugin to Plugin
- move from matheval to mathex
- move from Flu_Tree_Browser to Fl_Tree
- fixed crash in Triangulate plugin

- 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

Fixed error in line curvatures

interpolation (which prevent geo transforms on extruded entities)

- display all control points in GUI for gmsh curves
- uniformize Fl_Value::step() values in GUI

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

- removed every "throw;", i.e., every throw that did not throw an actual exception.
  throw wihout args should ONLY be used in a catch{} to re-throw the same exception
  (for it to be handled in another catch clause)

- introduced GmshMessage callback class so that clients can easily implement
  their own message handling (see example in driverOCC.cpp)

  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
