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

  kernel-specific information
- better documentation of lists returned by extrusions

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

- fixed missing getShapeFunction/getGradShapeFunction + return all sf
  at once so we can implement MElement in term of these consistently
  (w or w/o FunctionSpace)

- can now merge multiple meshes and remove duplicate mesh vertices
  (useful e.g. when merging several STLs)

- added easy interface to create model-based postpro datasets on the
  fly + use this for mesh quality stats

   1) this removes the asymmetry in all the routines involving mesh
      elements associated with points

   2) it makes it possible to use point-based datasets in the
      model-based post-processing module

    PLEASE TEST --- ESPECIALLY THE INPUT/OUTPUT ROUTINES!
  **********************************************************

* made GModel::getEntities() more efficient and generalized its use

  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

do this, but some people actually do...)
- added some attractor examples

make it easier to see when char lengths are bad

A minimal Gmsh "null" model can now be embedded with no external dependencies

make parser embeddable in code with other parser (yy->gmsh_yy)
more work on headers
fixed lots of gcc warnings

fix position of BoundaryLayerPoints

removed gobal meshSize in GMODEL: for now use CTX.lc, which is correctly
updated when multiple files are merged

cleanup msg

Plane surfaces are now recognized and the
usual gmsh "cross" is drawn correctly

prepare for extrusion
