Set up documentation for each run

[ingvildeb]

We should have a document where each run is briefly documented. What to be documented for each run:

• run name
• short description of what is being tested (e.g. "tested addition of one bilateral landmark at the dorsal tip of the inferior colliculus")
• output folder path
• short description of the result evaluation (according to landmark checklist, see issue: https://github.com/ingvildeb/DeMBA_scripts/issues/5)

This can be done in google doc, word doc, or somewhere else (no strong opinion here).
