Its basename is the basename of the name of the .dot file.

Also provide a =--gen-register= option generates such a registring ml
file. --gen-register also generate a state.ml skeleton file.

The Makefile test/Makefile.inc also suppose that the types of the state
is defined in state.ml

To do that, I've reorganized the code

Test: with ocaml 4.08, it is impossible to load the same function twice.
Hence the need to define p.mli files for graphs with several nodes.

Also, track missing files and the alea-coloring exemples.

- the move_count node was wrong (missing parenthesis)
- the lemma an the theorem only holds for locally central unfait demon

Moved the python environment into 'tools', added Project object in the python environment alongside minor changes, created some scripts to test the environment, and changed make_dot function in topology.ml such that it removes the path of a file before using it as graph name.

Added tools/test/skeleton to test gg and gg-deco. Made also small modifications to make_dot (in topology.ml)

(I forgot to change it everywhere)

Added an error message when neato doesn't work (when using "gg UDG -du|-dur ...") that is affected by --silent (aka. -s)

Debugged, renamed CommomGraph ClassicGraph, placed all the UDG utils from RandomGraph into a new module, enhanced "gg <command> -s" such that is has effect on warnings, removed "rand" function

Added comments, enhanced 'gg -h', changed some names, replaced an UDG tool function with another, and other minor things.

The generation scheme is now makes it easier to write oracles that do
not depend on the topology.  The idea is to generate an oracle
(specific to the graph) that includes a file that the user should
provide, and which ougth to define a generic oracle, i.e., depending
on m and n (process and actions numbers).
