[Gmsh] gmsh 2.0

[Dmitry Firsov]

Dear GMSH Developers,

Probably that was not grate idea to remove isotropic algorithm from gmsh 
2.0. I was able to generate with isotropic algorithm meshes with a lot 
higher quality then Netgen gives (the quality: smallest distribution of  
area/volume ratio along the mesh).  Also gmsh 2.0 is unable to generate 
a mesh (it is crashing), when gmsh 1.65  with isotropic mesh generator 
gives a good result. Attached geo file shows exactly that problem... Of 
cause isotropic mesh generator sometimes is crashing and takes to much 
CPU resources, but it gives good results.

Best,
    Dr. Dmitry Firsov
