Basic error handling:

Notes

Things I'm thinking.

It would be awesome to have a custom component that all the monthly surveys inherit from, since their functionality will be the same I think. The only tricky thing is the forms are custom, and that puts a damper in reusability. --> Timebox explore in #380

~As discussed on slack #react, I wasn't sure how to handle the requests to the survey endpoints. It doesn't make sense to me to invoke Redux since survey data is very much only used in the scope of the modal being open. This is what I have that is working, for now. Open to discussion!~ Decided on making requests from component.

Testing Instructions

In utils change the startYear (line 192) in getAprilSurveys to 2018. Visit http://localhost:8000/survey/?beekeepers and click one of the April (APRIL) surveys. Fill out the survey if it doesn't exist, else see the results display.

Other survey listings should open an empty popup which will be subbed in with their survey form components when they exist.

Just merged #406. This will need to be rebased atop develop to resolve the merge conflicts.
