set_path_cp_config_from: Set the location to a config file
Description
If a remote location is specified, the file is downloaded to a temporary
location and the path to this location is returned. If NULL, we'll resort
to a default config. We'll perform some checks on the existence of the file
too.
Usage
set_path_cp_config_from(path_cp_config_from, path_root, verbose = TRUE)
