        Logic Language Elements:
            x                   variable
            f(t1, t2, ...)      functor
            P(t1, t2, ...)      predicate, where t1, t2, ... are terms
            not A               negation
            A and B             conjunction

        Commands to work with axioms and lemmas:

            lemmas              lists all existing lemmas
            axiom <formula>     adds formula to axioms' list
            lemma <formula>     proves and adds formula to lemmas' list
            remove <formula>    deletes formula
            reset               resets lists of axioms and lemmas
