Oath.js

`new Oath(executor)`

The Oath constructor. It takes a single function argument executor. Returns a new Oath when invoked with the new keyword.

`executor(resolve, reject)`

The defining function for an Oath. It is passed two callbacks when invoked by the Oath constructor:

`resolve(resolutionValue)`

resolve, if/when invoked, will resolve the Oath with the value passed to it. If resolutionValue is also an Oath, the resolution or rejection of resolutionValue will cascade to the Oath being created.

`reject(error)`

reject, if/when invoked, will reject the Oath with the value passed to it. This should be used only with instances of Error or one of its subclasses (e.g., RangeError).
