| An ExecutionStatementValidator is an object that is
handed a ConstantAction and asked whether it is ok for
this result set to execute. When something like
a trigger is executing, one of these gets pushed.
Before execution, each validator that has been pushed
is invoked on the result set that we are about to
execution. It is up to the validator to look at
the result set and either complain (throw an exception)
or let it through.
