* add a cmakeLists for the book to add a project in visual studio so the book can be edited with the code
* remove trailing whitespace
* remove restrictions on MSVC and use a globbing expression in finding the files. Also add a check to make sure book directory exists which seems to be important on appveyor
* apparently doxygen was updated and the old download script no longer worked
* try a different url for the older download
* use github source tar
