@balupton's flow control and testing approach

Uses bal-util for flow and joe for testing. Feedback welcome. Inspired by this gist.

Pre-Requisites

npm install -g coffee-script
npm install bal-util joe

Example 1 returns:

$ coffee bal-util-flow-1.coffee
joe
joe ➞  moods tests
joe ➞  moods tests ➞  should do something useful with moods
joe ➞  moods tests ➞  should do something useful with moods ✔   
joe ➞  moods tests ✔  
joe ✔  

1/1 tests ran successfully, everything passed

Example 2 returns:

$ coffee bal-util-flow-2.coffee
joe
joe ➞  moods tests
joe ➞  moods tests ➞  should do something useful with moods
joe ➞  moods tests ➞  should do something useful with moods ✔   
joe ➞  moods tests ✔  
joe ✔
