Proper treatment of expressions with free arguments.

Roundup bound.

Tests for sublocale command.

Sublocale command.

Command to add dependencies, fixed processing of dependencies.

Fixed strange indentation.

add Algebraic and Universal to imports

separate run and cases combinators

renamed lemma compact_minimal to compact_bot_minimal; renamed compacts to approximants

renamed lemma compact_minimal to compact_bot_minimal

Use standard export function.

Expression types cleaned up.

Test for term patterns added.

Expression types cleaned up, proper treatment of term patterns.

check for more common errors first

improved error msg; tuned

removed "log" again, as IntInf.log2 already exists.

Some regression tests for theorem statements.

Enable switching to new locales during session.

Read/cert_statement for theorem statements.

Generalised activation code.

More ramifications of removal of 'includes' element.

tuned;

eliminated finish_proof, keep pre/post normalization of results separate;

future: norm_proof after make_result reduces memory requirements but increases runtime (factor 1.5 for both for HOL with proof terms);

Regression tests for new locale implementation.

add_locale functional.

Added a line that was missing from the definition

added binary logarithm

Strange. The proof worked in the 2008 release. In order to make it work now, the last line of the proof must be moved up two places. In other words, the first proof step is now returning its subgoals in a different order from before.
