1) Fixed bug in Defs.merge_edges_1.
2) Major optimization of Defs.define: do not store dependencies between constants that
cannot introduce cycles anyway. In that way, the cycle test adds almost no overhead to
theories that define their constants in HOL-light / HOL4 style.
3) Cleaned up Defs.graph, no superfluous name tags are stored anymore.
For Isabelle2005:
- update course material slides to new theory headers (Tobias)
- shell script to convert to new theory headers
- attach additional ML code to consts_code section (Stefan)
- modular generation of ML code with structures (Stefan)
- Library/ExecutableSet.thy (Stefan)
- a global "disprove" menu item both as an action and (if it can be done)
as a setting (Stefan & Tjark)
- convert fast_lin_arith.ML and cooper_dec.ML to use IntInf (Tobias)
- update or remove ex/MT (Larry)
- Include IsaPlanner? (Larry to co-ordinate)
- rules -> iprover (Stefan)
- ball, bex and setsum congruence rules (Tobias & Stefan)
- remove this file (Tobias)
