Treasure Data to Slack bridge.

This is a little Sinatra app that bridges between Treasure Data's HTTP PUT result output functionality and Slack's Incoming Webhook API.

So, it's like

 ---------------------   HTTP(S) PUT   ----------                      -------
| Treasure Data table |-------------->| td2slack |------------------->| Slack |
 ---------------------  abc.com/hello  ----------   render hello.erb   -------

• Set the env variable SLACK_WEBHOOK_URL to be a Slack incoming webhook URL.

• The path of the app corresponds to the ERB template under /views. So, if you specify the path /daily_stats, the template /views/daily_stats.erb is rendered as a Slack message.

• The special variable @td holds the table data as a JSON whose keys are column names and values are column values. Ex: if the result output is

  col1	col2
  100	hello
  200	world

  Then, @td is

  {"col1" => [100,200], "col2" => ["hello","world"]}
