Add viewhelper for header / footer elements

Currently, it is necessary to extend the class defined in plugin.tx_pdfviewhelpers.settings.config.class, overwrite the Header() or Footer() method or both and set the custom class in plugin.tx_pdfviewhelpers.settings.config.class

The Header() and Footer() methods are called for every new page added.

I think this solution only works if you have a static header and footer. but what if you want to add dynamic data like data from your model?

I think @macjohnny is proposing a feature similar to this:

<pdf:document>
   <pdf:header>
       <pdf:text>Some headline text: {yourVariable}</pdf:text>
   </pdf:header>
   <pdf:footer>
       <pdf:text>Footer, we are on page {currentPage}</pdf:text>
   </pdf:footer>
   <pdf:page>
       <pdf:header>Maybe we can overwrite header and footer on pages?</pdf:header>
   </pdf:page>
</pdf:document>

It should be possible to define header and footer on document level. Probably there should also be the possibility to overwrite header and footer on page level and variables like {currentPage} should be provided. In this scenario you could use dynamic data from your model.
I am not sure however how this feature could be implemented. Maybe it is possible to store a reference to e.g. HeaderViewHelper and then render its children on each page with a new set of variables like {currentPage}.

That would be great! I would sponsor €100 for something like this.

I started progress on this one and created a working example: bb942c3

It seems to be easier than expected, although it still needs some effort until it is ready to be used.

This is implemented and tested in the current develop branch and will be released as part of pdfviewhelpers v2.

@Gernott I just released pdfviewhelpers v2, it contains header and footer ViewHelpers and lots of other features. If you still feel like sponsoring, a contribution would be very welcome!
