BCG a8bed52097 Added java.util.Formatter implementation. Basic/common formats work,
such as %s, %d, %x... also width, left justify, zerofill flags are
implemented. Many of the other formats do not work, see the comments in
avian.FormatString javadoc and look for FIXME and TODO items for more
information on features that are known to not work correctly.
