updating to the development version of roxygen2, because with the

current stable version (5.0.1) devtools::check(manual = TRUE) as well as

an error (or warning) for "checking PDF version of manual" (namely:
"LaTeX errors when creating PDF version.
This typically indicates Rd problems."). This was a very frustrating
bug, it took hours...
