/// \brief
/// The IExpressionProcessor interface can be used to process the nodes in an
/// Expression tree. It declares an process operation for each concrete class in
/// the Expression hierarchy. Providers or client applications can create
/// classes that realize this interface to do something meaningful with an
/// Expression hierarchy. For example, an RDBMS feature provider implements a
/// processor class to convert an Expression hierarchy to the SQL equivalent
/// syntax.
