Modular API for ePub books, currently in MVP state.

Let's say you want to merge 2 books and reorder their chapters accordingly. You can either script against rootfile.opf directly or use some wysiwyg and reorder manually, however, these are boring options!

• C++17 compiler(VS2017+ for Windows)
• premake5

E.g. on Linux:

$ premake5 gmake
$ make config=linux_release

• don't overwrite current book's <manifest> resources not referenced in <spine>
• proper error handling
• move internal book representation into ::detail
• XSDs? :\
