Proposed changes

Adds an example for a relatively simple subsurface simulation case. In addition to the run script, notable additions are the geometry (two wells and two elliptic fractures) and BCs and ICs based on thermal gradient/hydrostatic pressure/lithostatic stress.

No testing as of yet.

Partial review, I have covered everything except from geothermal_reservoir.py, but ran out of time and energy. Hopefully I can complete the review tomorrow.

From what I have seen so far, this will be very useful. There are some topics I think we should discuss in person (see detailed comments), but I have no significant concerns at this stage.

Review of the run script. Nice work!
