This class currently just does one thing; it adds a right-click menu item in the Publish tab that saved PNG thumbnails of all the "day" pages of a SHRP Pupil's book. These are used in the corresponding "Teacher's Guide". It is built as an MEF "part", exporting what Bloom needs (the menu item) and importing what it needs (e.g. the contents of the book, an html thumbnailer) Currently (In Dec 2013), it isn't actually an extension because it doesn't have its own DLL. But it does demonstrate that we could trivially have extension dlls coming with templates, in separate DLLS. The key is keeping the dependences to a minimum so that extension don't break with each version of Bloom.
