Stability : experimental

Portability : non-portable(import Logic.Logic)

Here is the place where the class Logic is instantiated for CspCASL.

Also the instances for Syntax an Category.

{-

todo:

- writing real functions

- Modul Sign.hs mit CSP-CASL-Signaturen und Morphismen, basiernd auf CASL.Sign

CSP-CASL-Signatur = (CASL-Sig,Menge von Kanalnamen)

CSP-CASL-Morphismus = (CASL-Morphismus, Kanalnamenabbildung)

oder nur CASL-Morphismus

SYMB_ITEMS SYMB_MAP_ITEMS: erstmal von CASL (d.h. nur CASL-Morphismus)

- instance Sentences

S�tze = entweder CASL-S�tze oder CSP-CASL-S�tze

Rest soweit wie m�glich von CASL �bernehmen

- statische Analyse (gem�� Typ in Logic.Logic) schreiben

und unten f�r basic_analysis einh�ngen

K�r:

- Teillogiken (instance SemiLatticeWithTop ...)
