Used by the Expression Manager for resolving any variable references encountered in an expression, for setting the values of variables which are targets of expressions and for being notified of externally triggered changes in variable values. A VariableResolver implementation must dispatch a VariableChangeEvent of type "variableChangeEvent" whenever the value of a variable managed by the resolver changes.
