Enhancement needed to be able to change edge/arrow weight

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use generate() to create a new graph. All edges will be initialized with
 default weight 1.0
2. Try to create a more "interesting" graph from the above by assigning
random weight to existing links.
3. To do so you need to know the internal representation of the graph,
which defeats the purpose of the nice graph class

What is the expected output? What do you see instead?

- expected to see a set_weight((n1, n2), weight) method (or similar).

What version of the product are you using? On what operating system?

- 1.0/1.1(HEAD), Linux

Please provide any additional information below.

Would be nice to have a more extended generate() with optional weight
envelope as argument. Use of a uniformly distributed random number would be
adequate. The signature may be. (I can write this tomorrow, if you want,
and submit it.)

Issue accepted. A patch would be very nice indeed as I'm a bit overworked now.

Don't forget to tell me your full name so I can give you the credits for this. 
Cheers.

Here is the patch, implementing both. Please let me know if you see any issues 
with
it. I tested all the edge related features, but I have not tested it for arrows.
