Implement Header/Footer Capabilities

[keerl]

In order for this plugin to be an alternative to RadListView, one of the features missing is being able to make a header and footer easily.

It would be nice to have reserved template keys for header and footer build-in.

To be clear it is already possible. Use a "header" or "footer" templates.
However the real usecase is to have the binding context of the listview and not the of the item.
Right I don't really need so not a priority to me.
But obviously anyone who wants to make a PR is welcome.

So you're saying it's possible by using templates currently, but you would have to have a "header" and "footer" item in the data that is being bound to the CollectionView? I figured that would be the case, I would just ideally want a more friendly way to do it, like RadListView does. I may take a crack at this eventually. I just created this as more of a wish-list sort of item to keep track of.

Yes good wishlist though!
