* Step 1: InnermostRuleRemoval MAYBE
    + Considered Problem:
        - Strict TRS:
            f(f(x)) -> b()
            f(g(a())) -> a()
            g(x) -> f(g(x))
        - Signature:
            {f/1,g/1} / {a/0,b/0}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {f,g} and constructors {a,b}
    + Applied Processor:
        InnermostRuleRemoval
    + Details:
        Arguments of following rules are not normal-forms.
          f(g(a())) -> a()
        All above mentioned rules can be savely removed.
