####Vow.promise()#### Create promise

var promise = Vow.promise();    

###Promise API### ####fulfill(value)#### Fulfill promise with given value

promise.fulfill(value);

####reject(reason)#### Reject promise with given reason

promise.reject(error);

####isFulfilled()#### Returns whether the promise is fulfilled

promise.isFulfilled();

####isRejected()#### Returns whether the promise is rejected

promise.isRejected();

####isResolved()#### Returns whether the promise is fulfilled or rejected

promise.isResolved();

####then([onFulfilled], [onRejected])#### Arranges for:

• onFulfilled to be called with the value after promise is fulfilled,
• onRejected to be called with the rejection reason after promise is rejected.

Returns a new promise. See Promises/A+ specification for details.

promise.then(onFulfilled, onRejected);

####fail(onRejected)#### Arranges to call onRejected on the promise's rejection reason if it is rejected. ####spread([onFulfilled], [onRejected])#### Like "then", but "spreads" the array into a variadic value handler.

###Vow API### ####isPromise(value)#### Returns whether the given value is a promise.

####fulfill(value)#### Returns a promise that has already been fulfilled with the given value. If value is a promise, returned promise will be fulfilled with fulfill/rejection value of given promise.

####reject(reasonOrPromise)#### Returns a promise that has already been rejected with the given value. If value is a promise, returned promise will be rejected with fulfill/rejection value of given promise.

####resolve(value)#### Returns a promise that has already been fulfilled with the given value. If value is a promise, returns promise.
