/**
Factory interface for creating simplifiers.
The use of a factory allows delaying the creation of the dependent_expr_state
argument until the point where the expression simplifier is created.
This is used in tactics where the dependent_expr_state is a reference to the
new tactic.
Alternatively have a clone method on dependent_expr_simplifier.
