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

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.
