/*
 * PinkySwear.js 2.2.2 - Minimalistic implementation of the Promises/A+ spec
 * 
 * Public Domain. Use, modify and distribute it any way you like. No attribution required.
 *
 * NO WARRANTY EXPRESSED OR IMPLIED. USE AT YOUR OWN RISK.
 *
 * PinkySwear is a very small implementation of the Promises/A+ specification. After compilation with the
 * Google Closure Compiler and gzipping it weighs less than 500 bytes. It is based on the implementation for 
 * Minified.js and should be perfect for embedding. 
 *
 *
 * PinkySwear has just three functions.
 *
 * To create a new promise in pending state, call pinkySwear():
 *         var promise = pinkySwear();
 *
 * The returned object has a Promises/A+ compatible then() implementation:
 *          promise.then(function(value) { alert("Success!"); }, function(value) { alert("Failure!"); });
 *
 *
 * The promise returned by pinkySwear() is a function. To fulfill the promise, call the function with true as first argument and
 * an optional array of values to pass to the then() handler. By putting more than one value in the array, you can pass more than one
 * value to the then() handlers. Here an example to fulfill a promsise, this time with only one argument: 
 *         promise(true, [42]);
 *
 * When the promise has been rejected, call it with false. Again, there may be more than one argument for the then() handler:
 *         promise(true, [6, 6, 6]);
 *         
 * You can obtain the promise's current state by calling the function without arguments. It will be true if fulfilled,
 * false if rejected, and otherwise undefined.
 * 		   var state = promise();
