README: fix mapLimit example
add async to travis
nudge travis to build
Node 0.6 and 0.8 are not supported for latest async
Point at caolan repo / Travis build - assuming that will be setup
pass params from doUntil/doWhile callbacks to the test function
make done callback function (instead of function-expression): dont create it new on each iteration
Update README.md

Added comment to waterfall example
Passing an object to .series() may lead to unexpected behavior

Just a friendly reminder for devs that pass an object to `series()`.
There are platforms that will execute the functions in seemingly
random order. If you or your testsuite rely on order of execution,
it's better to just use an array of functions.
Update async.auto example in README.md 

async.auto does not actually run (because callbacks not called) and does not illustrate main features of async.auto. Updated to use callback and console.log results.
Added additional example for async.each

Changed the order of the asyn.each examples.  The simpler version is first.  The more detailed version is second.

added seq function: natural to read version of compose
added comment in example.
Merge branch 'master' of github.com:caolan/async into feature-seq
Add invalid passing async.memoize() test

This demonstrates the problem described in #304
Test for correct async callback behaviour
Refactor memoize test to use async function

Makes example async function async by using async.setImmediate
Refactor unmemoize test to use async example

Uses async.setImmediate to make example async
Refactor memoize custom hash test

Removes assumption that memoized result is synchronous
