Improved DataBinder Javadoc for xxx*yyy pattern matching

The default documentation does not mention xxx*yyy pattern matching,
which is, however, supported by PatternMatchUtils. Such a pattern
can be useful for matching nested properties in all elements of a
collection, e.g. property[*].nestedProperty.
