Tapestry

Okay so I've committed in this branch what I believe to be enough work to get the GoogleSurveysController to synchronize a survey set up by a researcher to read data from a specified spreadsheet made available via Google's Oauth2. Now I am just wondering what is up with the GoogleSpreadsheet model and corresponding controller... What are these used for?

My latest commit attempts to make the GoogleSpreadsheetController work according to my best guess. I was able to get it to do stuff, and now it reports errors a bit more consistently too.

I've made some controller tests similar to what I'd done for Open Humans, but proper testing of the google surveys and spreadsheets stuff is going to take some doing: there's nothing existant to upgrade to Oauth2, so they'll have to be conceived from scratch. Do we want to include as part of this story some kind of model testing of google survey and spreadsheet synchronization and so on, which actually tries to simulate a spreadsheet with data?
