make tests use the test db connection
add readme instructions on running the tests
add rake to Gemfile
refactor tests to use let for the shared object
don't define a primary key on the table

we can get duplicate ids because we duplicate original tweets, the true
PK would consist of all the columns
add another column for storing the tweet id

gave up trying to teach Active Record relational theory
rename websockets.rb to eventsource.rb
query the database for the most recent and retweeted
Time.now.utc is redundant
handle more twitter api messages
use a 64bit int to store tweet ids
use a table instead of a list to display the tweets
run more commands with bundler
substract 1 from the retweet number for the original
delete twitter API keys
print watched topics
move schema and eventsource under tweetwatch/
add another entry that retweets a 'new' status
make refresh interval a constant
add some notes about the overall design
