Data analysis git update:

Nolan's instructions for analysts:
git fetch
git checkout beamtime_september_1_2024
and then to push any additional fixes you make:
git add -u //or 'git add <filename>' for individual files
git commit -m "fix..."
git push origin beamtime_september_1_2024
and to get fix someone else made:
// make sure you don't have important unsaved changes (can 'git stash' if u want to clear any current unimportant changes)
git pull origin beamtime_september_1_2024

 There is a more general page for understanding the basic suite analysis here: https://confluence.slac.stanford.edu/display/LCLSDET/Introduction+and+orientation

It points to Nolan's git documentation and a variety of other things, most relevantly a page for the coming beamtime that Bhavna is working on: https://confluence.slac.stanford.edu/display/LCLSDET/Sept1+beamtime+analysis+instructions
