Common Node throws exception when compared to non-node

[GoogleCodeExporter]

If you compare common (core/pygraph/mixins/common.py) to anything that's not a 
node, it will throw an AttributeError.

This is really inconvenient when using libraries (in this case, specifically 
pyyaml) that check equality between things that may not be the same object.

Attached is a fix. It tries to compare the nodes and if it throws an attribute 
error, they must not be the same type and it returns false.

With this fix, you can serialize a graph using pyyaml without any exceptions 
being thrown.
