> Add features to FileFilterUtils that allow for filtering collections and maps of files
that are not retrieved from directories in the standard manner. This feature could be useful
for filtering files that are provided by the user or that do not all reside in the same directory.

> Example:
> List<File> files = getUserSelectedFiles();
> List<File> xmlFiles = FileFilterUtils.filterList(Arrays.<File>asList(new
File("A.txt"), new File("B.xml")), FileFilterUtils.suffixFileFilter(".xml"));
