automatic mesh generation

[GoogleCodeExporter]

Attached find a first draft of the mesh utils patch.

Usage
-----

Study convert.py, that shows a simple example:

$ python convert.py 
General geometry information:
  points: 7
  lines: 18
  surfaces: 20
  volumes: 8
Physical entities:
  surfaces (boundary conditions):
    1: surface numbers [15, 29, 39, 53, 63, 77, 87, 100]
  volumes (regions):
    100: volume numbers [1, 2, 3, 4, 5, 6, 7, 8]
Generating mesh using /usr/bin/tetgen -pQAq1.000000 -a0.300000 tmp/t.poly
Reading mesh from tetgen...

Writing mesh to tmp/t12.msh: 100% |#############################| Time:

You need gmsh and tetgen executables to have installed. It takes
database/t1.geo.sphere-tri, runs it through tetgen, parses the result back,
and writes the mesh to tmp/t12.msh, which is and input file for gmsh.

Now I need to write a new output function to export to the .mesh format.

License note: I relicense all my code to new BSD. And the progressbar is

So I will move the progressbar into sfe/base/, ok?

Afternoon is here = maintenance of our network, my e-mails stop working...

Yes. And fix it's license according to:

No problem. Sure I can license it under BSD.

I noticed you committed the patch. We need to change it's license (it's using 
GPL) -
I as the author can easily do that - let's use the same license as sfepy, i.e. 
BSD.

And also more refactoring is needed, before this issue can be closed.
