 * @brief A class for listing files and directories to check.
 * This class creates a list of files to check. If directory name is given then
 * all files in the directory matching the filter will be added. The directory
 * can be also added recursively when all files in subdirectories are added too.
 * The filenames are matched against the filter and only those files whose
 * filename extension is included in the filter list are added.
 *
 * This class also handles filtering of paths against ignore filters given. If
 * there is ignore filters then only paths not matching those filters are
 * returned.
