removed obsolete context;

turned 'context' into plain thy_decl, discontinued thy_switch;

tuned proofs;

removed mapping; added reinit;

simplified LocalTheory.exit;

Improvement to classrel clauses: now outputs the minimum needed. Theorem names: trying to minimize the number of multiple theorem names presented

deleted all uses of sign_of as it's now the identity function

tuned;

tuned Variable.trade;

introduces canonical AList functions for loop_tacs

minor refinements

redundancy checkes includes eta-expansion

improved syntax

added bounded_linear and bounded_bilinear locales

no special treatment for cygwin (this is supposed to be actual cygwin, not win32 polyml within cygwin);
