Function bed_reader::sample_files

pub fn sample_files<AnyPath0, AnyIter1>(
    path_list: AnyIter1
) -> Result<Vec<PathBuf>, Box<BedErrorPlus>>where
    AnyPath0: AsRef<Path>,
    AnyIter1: IntoIterator<Item = AnyPath0>,

Returns the local paths to a list of files. If necessary, the files will be downloaded.

SHA256 hashes are used to verify that the files are correct. The files will be in a directory determined by environment variable BED_READER_DATA_DIR. If that environment variable is not set, a cache folder, appropriate to the OS, will be used.
