TODO list:

Avoid bugs and improve compilation

[] Add explicit interface (blocks) for external or dummy procedures in FORTRAN code. This is creating this warning Could not found the body of interfaced routine
[] Check compilation warning getarrdims:warning: assumed shape array, using 0 instead of '*'
[] Check compilation warnings Warning: Possible change of value in conversion and Type mismatch in argument. This already created some issues in some of the FORTRAN programs by transferring Real*8 to Real arrays.
[] Clean a bit the code Warning: Label 4 at (1) defined but not used and Warning: Unused dummy argument.
[] Initialize arrays Warning: ‘####’ may be used uninitialized in this function

Improve algorithms and testing

[] Complete the estimation part for n node, blocks or polygons (kt3D program)
[] Fix the issuaes with gaussian anamorphosis and do more testing.
[] Do more testing on VTK selection
[] Do more testing on desurvey drillhole

User interface and help

[] Simplify examples
[] Do all in one example
[] Review doc string
[] Write user manual
