I can't believe how difficult using this library has turned out to be. 
I'm very near just giving up on it entirely.  After hours and hours of 
excruciating pain and suffering I have managed to get everything working 
that I need except for one thing.  Now that I have changed to using 
subgraphs, as required for being able to retrieve a subgraph at all, I 
have run into a brick wall.

I can't write graphviz output anymore.  The function that now gets 
called when I attempt to requires a graph_name property that just plain 
isn't there.  I can find how to retrieve it by looking in the code that 
thinks it should be there...but there is nothing anywhere that helps me 
figure out how to set the damn thing; not in the docs and not anywhere 
in the code that I can see.  So I'm at an impasse unless someone can 
tell me exactly where in the docs I'm supposed to be able to find this 
information.

Not only that.  I know for a fact this thing has a memory leak.  The 
subgraph setup creates a subgraph somewhere inside the parent that I 
can't get to.  I can create subgraph after subgraph but there's no way 
to destroy them!  Looking at the code that creates them it is quite 
obvious that they are created on the heap and my repeated creation of 
them is going to pose a problem rather quickly.  Quite frankly, I can't 
understand how this API exists without a method to kill subgraphs.  This 
is a major flaw.

Boost is great, but I tell you....some of these libraries could REALLY 
use some work on the documentation side.  I'm going bald trying to 
figure this damn thing out.
