[Gmsh] cartesian grid tool

[Dario Martini]

Hi Christophe,

First I want to thank you for gmsh which is a very nice tool.
I have found an interesting code that makes a cartesian grid of an .stl 
model.
My interest is to make a high pressure die casting simulation using OpenFVM.
The problem about die casting is that 3D models generally are very 
complicated and can have dirty geometry, so is not so simple carry out a 
good mesh.
I have used MagmaSoft (that is considered the best software in die 
casting) for 5 years at work, and this software has a very robust 
cartesian grid mesher, unlike Procast (the second best) that, using an 
unstructure tetraedral mesh, may have problems in the preprocessing process.
So, as I'm not a programmer, I would like to ask you if is possible to 
implement a cartesian grid in gmsh.

Thanks in advance
