.SYNOPSIS
Control various actions to be taken on the RQDAassist repository/package.

.DESCRIPTION
The RQDAassist package repository is more complicated than some regular CRAN-compatible packages.
For instance, the RQDA packages and its dependencies have to be regularly cleaned up for testing 
out both binary and source installation options. Also, at this point, the package
is only working with R versions lower than 4.2. So when developing, one has to always remember to
use that version, when it's not the one pointed to by PATH. This script makes it easy to carry out
