Add optional callback to the settings object.

[DanielJohnsson87]

I'v added a callback to the settings object. It will run once the $.each functions is done.

Hey thanks for contributing! What's the usecase for this? That callback could get called thousands of times onresize.

Sorry for the bad explanation.

The usecase for me was to add a class to the elements effected after page load once the elements font-size is set. To prevent flash of unstyled content I've hidden all titles and in the callback I will add a animate-in/show css class to display the titles after the correct font-size is set.

I'm aware that the callback would run on every 'onresize'-event and I'm handling that on my side. But it didn't make much sense to add a callback to the plugin if it only fires sometimes.

Perhaps adding a variable to the callback to control if the callback should run once or every time could be a solution? The default being that the callback only runs one time?

Ah. I think I sorta understand. Might be kinda niche to your implementation. The need for a callback hasn't come up much in the last 5yrs. Do you have a CodePen or something showing what you're doing? I want to be sure I understand it completely.
