Compute the best size of the notebook, taking into account all the
different layout possibilities, and add a test checking that this works
as expected.

It seems better to organize the tests in different files and just
provide a common fixture-like class to reuse functionality.
Also use this as an opportunity to rewrite the tests to use Catch
directly instead of using CppUnit-compatible macros.
Finally, actually build these tests as part of the test suite.
Use the same format as is used by MSVS itself to avoid spurious changes when
modifying the files. Notably:
- Use DOS end of line format (0D 0A).
- Add UTF-8 BOM (EF BB BF) to the beginning of the files.
- Do not put CR LF at the end of the last line in the file.
