I do not have additional details here

@RBFraxinus do you have any additional information for this? Thanks!

[RBFraxinus]

@dce looks like this is just one attribute to add now: a boolean 'humanitarian' field. For validation purposes,the value of that field should be true for the other new humanitarian attributes/associations to be saved for a project.

@RBFraxinus This is ready for QA on staging.
