added generic_theory transaction;

commands 'use' and 'ML' now thy_decl; removed obsolete 'ML_setup' -- superceded by 'ML';

removed obsolete use_XXX; added ml_diag;

eliminated destructive/critical theorem database; simplified store_thm(s); removed obsolete smart_store_thm(s); tuned;

certify wrt. dynamic context; functional store_thm (wrt. thread data);

added map_theory_result, map_proof_result;

certify wrt. dynamic context;

eliminated non-linear access to thy1 and thy12c;

replaced 'ML' by diagnostic 'ML_command';

updated generated file;

simplified PureThy.store_thm;

replaced 'ML_setup' by 'ML';

* Eliminated destructive theorem database. * Commands 'use' and 'ML' are now purely functional; added diagnostic 'ML_val'.

eliminated quiete_mode ref (not really needed);

eliminated quiete_mode ref (turned into proper argument);

eliminated quiete_mode ref (unused);

eliminated quiet_mode ref of some packages (avoid CRITICAL setmp!);

added forget_structure;

eval_wrapper: non-critical version via unique Isabelle structure, proper forget_structure;

ml_tactic: non-critical version via proof data and thread data;

NAMED_CRITICAL;

unfold_locales now part of default tactic

import Main explicitly

dropped now superfluous ad-hoc adaption

not depends on Main any longer

accomodated to sledgehammer theory dependency requirement

only invoke interpret

updated generated file;

Context.>> : operate on Context.generic;

avoid rebinding of existing facts;
