Add PDF Viewer Support

[MLyons10]

I love how easy PDFPig is to use, and the continued work to improve and extend its functionality is so appreciated by everyone that uses it.

Are there any plans for a simple PDF Viewer control to be included with PDF Pig? Or is there a way to already do this?

Thank you for all of the work you've put into this, I look forward to seeing what future features may be added.
