Initial demo using LGI bindings
adg-demo: incremental update
Updated to last adg
Using canvas autoscale feature instead of hard-coded map
Added title block
Reenabled dimensioning

With the latest updates to the ADG sources, the drawing is slowly being
shaped. Actually the quotes are rendered, although there seems to be
some miscalculations hanging around in the named pairs code.
Updated to last adg

Dimensions are now properly rendered and handled. The current status is
yet in a better shape than the last one that used lgob bindings.
Merge branch 'lgi'

LGI bindings are now the preferred dependency for Lua bindigs for a couple
of reasons: they are working with ADG out of the box (nothing to install
apart LGI and ADG) and they have more mainstream acceptance.

The project is now a demo/test program of what can be accomplished with
LGI and ADG.
Updated license text to "real" GPLv3
build: updated build system

Actually the adg-lua project is only an example application on using the
LGI bindings with ADG. In other words, ADG and LGI works together out of
the box.
Split adg-demo into demo and piston

piston.lua is a module that defines the MVC of a generic piston.
demo.lua provides GTK+ make-up, populates the model and retrieves the
views.

This will simplify future work for the web application.
Renamed demo.lua to adg-demo.lua
doc: updated README and NEWS
build: bumped to version 0.1.0
