[CIG-SEISMO] .xyz format

[Dimitri Komatitsch]

Hi Julie and Anne,

By .xyz format do you mean a simple ASCII file with a list of model 
values for a regular x,y,z grid?
If so I think it would be useful to add this as an option to the 
official version of SPECFEM. In that case, Julie could you email me the 
files you mention below? we will then merge your modifications into the 
official source code.

Thanks,
Dimitri.
