Scrape river level information from the Environment Agency website, and republish it on Twitter.

Setup
=====

Create a conf/twitter4j.properties file, with the following Twitter properties:
    oauth.consumerKey=
    oauth.consumerSecret=
    oauth.accessToken=
    oauth.accessTokenSecret=

(you can get the various keys and tokens from Twitter at https://dev.twitter.com/apps)

The app is built with Play and Scala - install Play from http://playframework.org/, and
run with "play run".

To change the rivers that are checked, add new harvest targets via the web page (or set the defaultTargets
field in application.conf, wipe the database, and restart).

You can find ids via the website at http://www.environment-agency.gov.uk/homeandleisure/floods/riverlevels/.
