Well really what this does is give every field a default value of None. what that does is allow you to use value expressions even without a given default value. this part in the backend fixes validation.
Removing the spreadsheet.value.column and data.value.column so we just have value.column for both.
Improving the __str__ function in the ApiError class, to make debugging a little easier.
Adding a "validate_all" flask command, to help us track down any issues with current workflows in production (use this in concert with sync_with_testing)
Fixed logs of tests.
removed fact_runner.py, a very early and crufty bit of code.
