Discussion about the future directions for PopIt UI

[chrismytton]

We need to have a higher level discussion about the potential future directions for the editing interface for Popolo data. Do we continue to use the current PopIt UI, which hasn't so far proved to be generally useful. Do we repurpose YourNextMP's crowd-sourcing interface? Create a new simpler generic interface? Something else? This is more of a philosophical question rather than a technical one.
