New to programming and trying to understand it all.

Im running through the first Hello World tutorial here on the site. At the end of the Hello World screencast i add the the following code.

Code:

function Blog() {
    parent::Controller();
}

Its not explained, but i would like to know the purpose of this as i see no difference in the output of the view.

Thanks in advance.
