Straight No Chaser

NEW FEATURES

• 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 Changes are purely internal (higher-level polmineR functions have been replaced by lower-level RcppCWB functions, some tests were re-written).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).

MINOR IMPROVEMENTS

• 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.
