#60 Multiple tract/visit runs in HSC module

[msimet]

This pull request implements two new HSC scripts, StileMultiVisit.py and StileMultiTract.py, that allow us to analyze multiple visits or tracts together as one instead of running through each tract or visit individually. These work exactly as StileVisit.py or StileTract.py but produce one output file per SysTest no matter how many input visits or tracts are given.

Changes involve:

• New tasks and task runners for the two new script types
• Changing the contents of the 'CCD' column, which traditionally stored just the CCD or patch number for visits and tracts, to also use visitnum_CCDnum or tractnum_patchnum in the case where we are analyzing multiple visits and tracts
• Making the class methods getFilenameBase be static methods in some cases, so we can call them from the new filename creators in the Multi* versions to avoid duplicating code. This could also have been done through super, I think, but I'm less familiar with that and so didn't use it. If anyone thinks we should switch to that, or should just make all the getFilenameBase methods staticmethods just in case, let me know.

I do not think #60 work. Instead, we switched to #60a, so should we make a pull request for #60a?

[msimet]

Oh, right! I forgot about that.

I did some work on this branch to make it functional because I forgot about #60a, and looking at a diff I think this is more correct than #60a was (though #60a worked). Does this run for you? If so, I think I'd prefer to stay with this branch.

[HironaoMiyatake]

Sorry that I did not carefully check "#60a"! It works fine on may side, so it's almost reedy to merge.

I still have another concern. I found that the filename is too long to be saved when running all tracts in some field. What do you think the best way to treat this?

[msimet]

I added a quick fix for this (25ac3ad) and it seems to still work--does it fix your too-long-filename problem?

I got the the following error. Is it okay to replace os.pathconf('sys_test_adapters.py', 'PC_NAME_MAX') with os.pathconf('.', 'PC_NAME_MAX')?

[msimet]

I don't think that should cause a problem!

[HironaoMiyatake]

Okay, now it works. Please merge this to master.
