(LEG WORK) Re-Align UCERF3 Faults

[kwschultz]

We must re-validate the strike angle for the UCERF3 fault model. An unknown number of the faults have their strikes flipped by 180 degrees, meaning that they may slip the wrong direction.

A description of the process of re-aligning the faults is here:
http://schultz.physics.ucdavis.edu/research/fixing_faults.html

Refer to @johnmaxwilson on how to implement this with our python scripts. They are contained in the VQModels repository, read the README file.

Search for the proper strike angle using the USGS database: http://geohazards.usgs.gov/cfusion/qfault/query_main_AB.cfm. You must convert from a heading to degrees measured clockwise from north (e.g. N83W to 277 degrees).

The script fix_faults.py and the section_strikes_with_fixes.txt are your tools for fixing things and documenting what you fix (the python scripts are well commented with instructions). We have already validated ~15 faults out of the 250 faults, consult Prof. Rundle on which ones are important, we don't necessarily have to fix all of them.
