Prototype introiff option for find_theorems. This feature was suggested by Jeremy Avigad / Tobias Nipkow. It adds an introiff keyword for find_theorems that returns, in addition to the usual results for intro, any theorems of the form ([| ... |] ==> (P = Q)) where either P or Q matches the conclusions of the current goal. Such theorems can be made introduction rules with [THEN iffDx]. The current patch is for evaluation only. It assumes an (op = : 'a -> 'a -> bool) operator, which is specific to HOL. It is not clear how this should be generalised.

replace cont2cont_apply with cont_apply; add new cont2cont lemmas

compatible with preorder; bot and top instances

updated generated files etc/isar-keywords.el and lib/jedit/isabelle.xml

added Philipp Meyer's implementation of AtpMinimal together with related changes in the sledgehammer-interface: adapted type of prover, optional relevance filtering, public get_prover for registered atps in AtpManager, included atp_minimize in s/h response;

removed code_name module

desymbolization with case selection

dropped duplicate lemma sum_nonneg_eq_zero_iff

fixed broken link

tuned header

class typerep inherits from type

use simproc_setup command for cont_proc

used named theorems for declaring numeral simps

clean up unsigned numeral proofs

detect error cases in mk_num, dest_num

add semiring_assoc_fold simproc for unsigned numerals

reorient simproc for unsigned numerals

reimplement reorientation simproc using theory data

deleted thm-attributes "fresh" and "bij" (not used); same features can later be implemented by simpler means

append prefs at end;

merged

adapted permutation functions to new overloading syntax (the functions are still "unchecked" because they are used in conjunction with type-classes)

use predefined preferences categories;

removed obsolete artifacts;

misc cleanup of auto_solve and quickcheck: tools are in src/Tools and loaded uniformly in HOL; preferences are configured in their proper place -- despite old misleading comments in the source; use predefined preferences categories; setmp preferences in-place;

renamed contrib/SystemOnTPTP/remote to lib/script/SystemOnTPTP, thus leaving contrib empty within the official distribution;

post Isabelle2009 version;

adjusted to change in code_wellsorted.ML
