VES example in example section

[m-weigand]

Feature Request

Whenever I touch a new geophysical method in teaching scenarios, I turn to the examples section of the homepage to quickly see what the current state of the corresponding forward operator is in pygimli.

While there are numerous examples scattered around in the examples and tutorials for VES modelling and inversion, I still think it would make VES more visible if there would be a comprehensive example under it's own section title "VES".

I started sketching out such an example (mostly by copy&paste from other parts of the documentation), but before proceeding I wanted to ask your opinion on this. Would this be worthwhile, and would you accept a corresponding merge request?

I am attaching the VES sketch.

VES is a nice method for demonstration purposes, while we are lacking of self-measured field data, particularly complex-valued ones. If there is a certain variety (synthetic, field, complex, laterally-constrained) we (including you) will be happy to create a VES section.

I am about using VES for the inversion section in the inversion part of the new User Guide. Actually, there are already two tutorials and two examples that could partly be moved into the User Guide or the VES section.
