The (weak) dependency on the polmineR package (it was in the 'Suggests:' section of the DESCRIPTION file) has been removed. Changes are purely internal (higher-level polmineR functions have been replaced by lower-level RcppCWB functions, some tests were re-written). Dropping the dependency has the advantage that there is a much clearer structure of dependencies now (RcppCWB -> cwbtools -> polmineR).
A remaining CLI formatting issue has been removed from the user dialogue for modifying the .Renviron file.
Unit tests used a test download of the United Nations General Assembly (UNGA) corpus from Zenodo. To reduce the time required for testing the package, a test download of the (much smaller) GermaParlSample copus is performed.
The `corpus_install()` function tried to ask for user feedback when not in an interactive session. The function now checks whether it is possible to ask for user feedback.
Part of the output of the `cwbtools::create_cwb_directories()` function did show if `verbose` was `FALSE`. Fixed.
