#RBFilePreviewer
##WARNING:
RBFilePreviewer does not work on iOS 6. QLPreviewController has been changed to use XPC. This prevents any customization, and I have not found any work arounds.
##Summary
RBFilePreviewer is a subclass of QLPreviewController. It is intended to make it easy to preview any QLPreviewItem. All you need to do is pass it the desired item(s) to preview to the appropriate initializer. You may use the provided RBFile class or any other class that conforms to QLPreviewItem (including NSURL).
##Dependencies
RBFile requires my NSURL+RBExtras category. It can be found in my RBCategories repository. RBFile is optional, so if you don't include it, then you don't need to include NSURL+RBExtras.
##Acknowledgments
RBFilePreviewer includes a couple icons from Joseph Wain. See Glyphish.com for more details. To get the 2x sizes of the icons, you must buy the Glyphish Pro icon pack.
