removed slow, slow_best methods; added clarify, clarsimp methods;

* Isar/Provers: intro/elim/dest attributes: changed intro/intro!/intro!! flags to intro!/intro/intro? (in most cases, one should have to change intro!! to intro? only);

rearranged setup of arithmetic procedures, avoiding global reference values;

lemmas [arith_split] = abs_split (*belongs to theory RealAbs*);

do nat pass theory value, but sg_ref;

avoid referencing thy value; rename_numerals: use implicit theory context; eliminated some simpset_of Int.thy (why needed anyway?);

much tidying in connection with the 2nd UNITY paper

strengthened force_tac by using new first_best_tac

Updating of some comments

*** empty log message ***

Univ no longer requires Arith (really it never did)

tuned;

corrected header

changed / to // for quotienting

changed / to // for quotienting; general tidying

renamed // to / (which is what we want anyway) to avoid clash with the new use of // for quotienting

deleted redundant proof
