Description : Central GUI for Hets, with display of development graph

Copyright : (c) Jorina Freya Gerken, Till Mossakowski, Uni Bremen 2002-2006

Maintainer : till@tzi.de

Stability : provisional

Portability : non-portable (imports Logic)

Conversion of development graphs from Logic.DevGraph

to abstract graphs of the graph display interface

A composition table is used when abstracting the graph and composing

multiple edges. It looks like this

'[("normal","normal","normal"),

("normal","inclusion","normal"),

("inclusion","normal","normal"),

("inclusion","inclusion","inclusion")]'

A ginfo can be created with initgraphs. The graph is then created with

addnode and addlink.

-}

{-

todo:

share strings to avoid typos

hiding of internal nodes:

internal nodes that are not between named nodes should be kept

display inclusions and inter-logic links in special colour

try different graph layout algorithms for daVinci (dot?)

close program when all windows are closed

issue warning when theory cannot be flattened

different linktypes for local and hiding definition links
