gracefully do nothing if the SPASS input file is already in DFG format

added sorted DFG output for coming version of SPASS

specify proof output level 1 (i.e. no detailed, potentially huge E proofs) to LEO-II; requires version 1.2.9

check "sound" flag before doing something unsound...

uniform treatment of syntax declaration wrt. aux. context (NB: notation avoids duplicate mixfix internally);

tuned;

more accurate class constraints on cancellation simproc patterns

tuned;

tuned Named_Thms: proper binding;

refined Local_Theory.declaration {syntax = false, pervasive} semantics: update is applied to auxiliary context as well;

more robust data storage (NB: the morphism can change the shape of qconst, and in the auxiliary context it is not even a constant yet);

uniform Local_Theory.declaration with explicit params;

tuned signature -- refined terminology;

slightly more explicit/syntactic modelling of morphisms;

correct import path

allow to build Probability and MV-Analysis with one ROOT.ML

removing dead code

ex/Simproc_Tests.thy: remove duplicate simprocs

use simproc_setup for cancellation simprocs, to get proper name bindings

tuned;

eliminated aliases of standard functions;

more standard attribute setup;

localized quotient data;

simplified/standardized signatures;

tuned signature;

uses IMP and hence requires its tex setup

merged

tuned text
