implements a property handler for use with an ::com::sun::star::inspection::ObjectInspector
which provides properties related to binding form control models to XForm bindings.
The handler introduces new properties to choose an ::com::sun::star::xforms::XModel
and a ::com::sun::star::xforms::Binding within this model. Additionally,
it introduces properties which reflect the different facets of the binding (e.g.
::com::sun::star::xforms::Binding::BindingExpression), so they can be changed
directly in the ::com::sun::star::inspection::ObjectInspector as if they were a
property of the form component which is being inspected.
The handler expects a value named "ContextDocument" in the context in which it is created.
That is, the ::com::sun::star::uno::XComponentContext used for creating the
CellBindingPropertyHandler is examined for a value with this name. If the object in this
value denotes a XML form document (indicated by supporting the ::com::sun::star::xforms::XFormsSupplier
interface), this document is used to do XML binding related work.
