Add integrated Thread functionality for delaying thread.start().

A DESCRIPTION OF THE PROBLEM :
In a scenario where a programmer wants a java.lang.Thread to begin after an arbitrary amount of milliseconds without yielding the program, the only way to do so is to start a new Thread that calls Thread.sleep() and starts the delayed thread.

Potential Syntax:
- thread.startIn(int milliseconds) or thread.delay(int milliseconds)

Current implementation:
        new Thread(new Runnable() {
            @Override
            public void run() {
                try{
                    Thread.sleep(8000);
                } catch (InterruptedException e) {}
                new Thread(runnable).start();
            }
        }).start();
