This class was created because of this Stack Overflow question:

Many times I was googling for [Brian Cline's](https://stackoverflow.com/a/254543/3133859)answer. And as many times I copied it, that many times I was extending it for my needs.

**But not again.**

I have rewritten and extended the class, and the result is this package!
