Moved the centre IDs into their own namespace
Pulled together two utility functions to grab the webpage for the centre with the supplied ID and parse that webpage to extract the data. Both pretty fragile, relying on arbitrary form POST parameters and existing HTML structure. It'll probably be fine for the next few days?
Quickly pulled together a not-smart way of pulling the data down for all the IDs, then exporting it to a .csv file. Ran it only to discover an annoying typo in the keys in get-centre-html meant that the same school was returned all 7411 times. SIGH. Fixed, will re-run in the office.
