remove duplicate lemmas

new lemmas

prefer theorem name over 'long_thm_list(n)'

prefer attribute 'unfolded thm' to 'simplified'

removed outdated comments

made non-co case more robust as well (cf. b6e2993fd0d3)

don't wrongly destroy sum types in coiterators

beware of multi-constructor datatypes (cf. 27c418b7b985)

beware of single-constructor datatypes, with no discriminators

more robust tactic to cover another corner case (added as example);

generalized data structure, for extension with SMT solver proofs

prefixed types and some functions with "atp_" for disambiguation

merged;

absorb final CLASSPATH as well, such that tools might provide that by elementary means, without the "classpath" shell function (e.g. kodkodi/nitpick);

more CHECKLIST;

more robust System.getProperty with default;

generate distribution classpath for cold-start application wrappers;

reverse orientation of ISABELLE_CLASSPATH;

propagate ISABELLE_CLASSPATH;

tuned comments;

clarified directory structure;

maintain classpath in more elementary manner: turn ISABELLE_CLASSPATH into -classpath option, so that all jars are covered by sun.misc.Launcher.AppClassLoader (e.g. relevant for loading add-on resources); ignore $ISABELLE_JAVA_EXT -- do not change java.ext.dirs;

more official initial class path according to sun.misc.Launcher;

provide main classpath again, notably for cold-start;

cold-start of main application even on Linux;

tuned proofs;

more explicit indication of 'done' as proof script element;

made tactic handle gracefully the case: codatatype ('a, 's) scheduler2 = Combine2 "'s => 'a" "'s => ('a, 's) scheduler2"

conceal definitions of high-level constructors and (co)iterators

conceal low-level noted facts (+ FIXME to get rid of the notes altogether eventually)
