Conversion of development graphs from Logic.DevGraph

-}

{-

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
