to do (mwj)

[markjessell]

1. Calc secondary age relationships for faults (A cuts B, B cuts C so A cuts C)
2. Exclude intrusions from supergroups
3. Look for thickness variations across faults
4. Record all data reoved by m2l
5. Group Faults by orientation
6. True fault offset with Z
7. Add estimated fault offset using strat offset for 0 & 1 offsets... (and add 50% of unit for others to be equivalent)
8. Calc true fault offset with fold limbs
9. Contact dip estimate with large Z variation
10. Save contact normals with polarity
11. Create geol/fault/oc group layes for all states

12. Add back code to allow arbitrary single polygon for ROI definition
