-#### parallel
+##### parallel
 
 # Execute an array of functions `fns` in parallel. The passed-in `callback`
 # will only be called when the all functions have call back.

  cb = -> count += 1; if count is fns.length then callback?()
  if fns.empty() then callback() else fn cb for fn in fns

#### queue

# Execute an array of function `fns` one after the other.
# The passed-in `callback` will only be called when the queue

  next = -> if fns.empty() then callback() else fns.shift() next
  next()

##### chain

# Execute an array of function `fns` on after the other, like a `queue`,
# but the different between them lies in the fact that a `chain` pass
