Content getter if elements are applied to Page

[korthjp17]

Do we want to write an extension to get the content from the first content block on a page? If the user isn't writing anything in the preview zone, there will be no content showing on the front-end. We can call it out in the Readme for the usage of the extension.

We have something that we can pull from an existing project, just wasn't sure if it should be included in this module.

I think this makes sense. Something along the lines of $this->hasExtension() to detect if it's implemented, then return the first content element if available. This can be baked out a bit more from a logic stand point, but minimally it would be first content element or the content zone.
