Special DataBinder to perform data binding from web request parameters
to JavaBeans. Designed for web environments, but not dependent on the
Servlet API; serves as base class for more specific DataBinder variants,
such as ServletRequestDataBinder.
Includes support for field markers which address a common problem with
HTML checkboxes and select options: detecting that a field was part of
the form, but did not generate a request parameter because it was empty.
A field marker allows to detect that state and reset the corresponding
bean property accordingly.
