[Pansophy] SNS PPU inspection traveler breakdown structure

[Gary Cheng]

Thanks Katherine.

Using SEC as an example, I would need to write the following travelers:
1. Visual inspection traveler --- for SRF QC group, i.e. Anne's group
2. Dimensional inspection traveler --- for Survey & Alignment group, end 
cans won't fit into our CMM machine
3. Weld inspection traveler --- for CWI
4. Instrumentation electrical checkout --- For Larry King's group
5. Vendor docs check --- for SOTR, CWI and leak check specialist
6. Pressure test and leak check --- For CMA

That's a lot to write for just the SEC. Then for the REC, I would need 
to write another 6 travelers...I don't think that's really what we want. 
But if PPU management prefers to have such a breakdown structure, I will 
write 12 travelers for the SEC and REC...someone please let me know.
