            The core idea of this library is to provide means for asynchronous program flow. The old-school way to do is,
            is to use callbacks. While this approach is simple and easy to understand, it has some disadvantages. As an
            attempt to relief and improve this, the promise-system was introduced. In principle it solves most of the
            problems found in the callback-approach; however it has some downsides as well:
                
            - Convolution of multiple principles
                Promises unite the ideas of asynchronous program flow and error handling.
            
            - Instant execution
                Creating a promise results in the instant execution of the given executor prodecure. While this might be
                convenient in some cases, it can be quite disturbing and counter-intuitive in others.
            
            - Broken typing
                The Promise system doesn't distinguish between an appending "then" (i.e. passing a function, which returns a
                new promise) and a closing "then" (i.e. passing a function, which has no return value). On top of that it
                allows returning simple values in an appending "then", which results in an implicit call of the executors
                "resolve"-function. The price for these "pragmatic" features is that the whole system can't be typed well.
                And even though JavaScript is not a strictly typed language, it was a quite questionable decision to design
                the promise system in a way, which breaks typing from the start.
            
            The deferral-system forseeks to solve these issues while retaining the advantages of the promise-system.
