		- `promise` is an object or function with a `then` method whose behavior conforms to this specification.

		- `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
		- `exception` is a value that is thrown using the throw statement.
		- `reason` is a value that indicates why a promise was rejected.
		- `settled` the final resting state of a promise, fulfilled or rejected.

		A promise can be in one of three states: pending, fulfilled, or rejected.

		Promises that are fulfilled have a fulfillment value and are in the fulfilled

		Promises that are fulfilled have a fulfillment value and are in the fulfilled
		state. Promises that are rejected have a rejection reason and are in the
		rejected state. A fulfillment value is never a thenable.

		Promises can also be said to resolve a value. If this value is also a
		promise, then the original promise's settled state will match the value's
		settled state. So a promise that resolves a promise that rejects will
		itself reject, and a promise that resolves a promise that fulfills will

		Chaining
		--------

		```js
		findUser().then(function(user){
		// user is available
		}, function(reason){
		// user is unavailable, and you are given the reason why
		});
		```
		The return value of `then` is itself a promise. This second, 'downstream'
		promise is resolved with the return value of the first promise's fulfillment
		or rejection handler, or rejected if the handler throws an exception.

		Chaining
		--------
		```js
		findUser().then(function (user) {
		return user.name;
		}, function (reason) {
		return 'default name';
		}).then(function (userName) {
		// If `findUser` fulfilled, `userName` will be the user's name, otherwise it
		// will be `'default name'`
		});

		The return value of `then` is itself a promise. This second, 'downstream'
		promise is resolved with the return value of the first promise's fulfillment
		or rejection handler, or rejected if the handler throws an exception.
		findUser().then(function (user) {
		throw new Error('Found user, but still unhappy');
		}, function (reason) {
		throw new Error('`findUser` rejected and we're unhappy');
		}).then(function (value) {
		// never reached
		}, function (reason) {
		// if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
		// If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
		});
		```
		If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.

		```js
		findUser().then(function (user) {
		return user.name;
		}, function (reason) {
		return 'default name';
		}).then(function (userName) {
		// If `findUser` fulfilled, `userName` will be the user's name, otherwise it
		// will be `'default name'`
		});
		```js
		findUser().then(function (user) {
		throw new PedagogicalException('Upstream error');
		}).then(function (value) {
		// never reached
		}).then(function (value) {
		// never reached
		}, function (reason) {
		// The `PedgagocialException` is propagated all the way down to here
		});
		```

		findUser().then(function (user) {
		throw new Error('Found user, but still unhappy');
		}, function (reason) {
		throw new Error('`findUser` rejected and we're unhappy');
		}).then(function (value) {
		// never reached
		}, function (reason) {
		// if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
		// If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
		});
		```
		If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
		Assimilation
		------------

		```js
		findUser().then(function (user) {
		throw new PedagogicalException('Upstream error');
		}).then(function (value) {
		// never reached
		}).then(function (value) {
		// never reached
		}, function (reason) {
		// The `PedgagocialException` is propagated all the way down to here
		});
		```
		Sometimes the value you want to propagate to a downstream promise can only be
		retrieved asynchronously. This can be achieved by returning a promise in the
		fulfillment or rejection handler. The downstream promise will then be pending
		until the returned promise is settled. This is called assimilation.

		Assimilation
		------------
		```js
		findUser().then(function (user) {
		return findCommentsByAuthor(user);
		}).then(function (comments) {
		// The user's comments are now available
		});
		```

		Sometimes the value you want to propagate to a downstream promise can only be
		retrieved asynchronously. This can be achieved by returning a promise in the
		fulfillment or rejection handler. The downstream promise will then be pending
		until the returned promise is settled. This is called assimilation.
		If the assimliated promise rejects, then the downstream promise will also reject.

		```js
		findUser().then(function (user) {
		return findCommentsByAuthor(user);
		}).then(function (comments) {
		// The user's comments are now available
		});
		```
		```js
		findUser().then(function (user) {

		// If `findCommentsByAuthor` fulfills, we'll have the value here
		}, function (reason) {
		// If `findCommentsByAuthor` rejects, we'll have the reason here
		});
		```

		If the assimliated promise rejects, then the downstream promise will also reject.
