graph-tool 1.1

Hi.

I'm pleased to announce version 1.1 of graph-tool. This version contains
a couple of new features, improvements and bug fixes.

Changes
=======

For a complete list of changes see:

https://projects.forked.de/graph-tool/log/trunk/src?action=stop_on_copy&rev=85&stop_rev=69&mode=stop_on_copy&verbose=on

The most important changes are

 * The whole way of editing/creating properties with python was
   completely redone. See the documentation for details.
 * Added graph property support (in addition to edge and vertex
   properties)
 * The entire graph is available to the python script when
   editing/creating vertex/edge/graph properties
 * Added --list-properties option
 * Newly created properties can now have any type
 * Faster startup

The documentation on the website was also properly updated:

clustering coefficient

Hi,

what's the difference between 

graph-tool --load z.dot \
--set-local-clustering-to-property=clustering \
--average-vertex-property="clustering|-"

and

graph-tool --load z.dot --global-clustering-coefficient=- ?

The results are not equal:

# average vertex property (clustering):
0.400881	0.001264

# global clustering coefficient:    
0.016429	0.000001

But the global clustering coefficient IS the arithmetic mean of the local
clustering coefficient of all edges, IIRC. I don't understand the divergence.

CU
Sven

Hi.

The global clustering coefficient is defined differently as the mean of
the local clustering coefficient. As stated in the documentation on the
website, the global clustering is given by
