Feature to read in tomography files with general anisotropic model definitions

[aakash10gupta]

tomography_model.xyz files can now have two more formats to accommodate the 21 parameters defining general anisotropy -

1. 25 columns (x y z c11 c12 c13 ... c66 rho)
2. 27 columns (x y z c11 c12 c13 ... c66 rho Qp Qs)

Header lines remain the same.

To read in any of these file formats the following should be set in the Par_file -

MODEL = tomo
ANISOTROPY = .true.

Some development points to note -

1. The 21 c values have been interpolated in the same way as Vp, Vs and rho values were being interpolated.
2. Bounds on the interpolated c values remain to be enforced.
3. The best choices of equivalent Vp and Vs values are still being thought of, as the code still needs these values for certain checks, etc.
