[deltacloud-devel] Driver instance states

[Bob McWhirter]

Howdy--

It's a non-functional change, unless you're a driver author, but I've  
created a more literate way to specify the states and transitions an  
instance might go through.

Looks like:
     pending.to( :running ) .automatically
     pending.to( :stopped ) .on( :stop )

The .xml representation is unchanged, as is the client that consumes  
it.  This purely makes writing drivers a tad easier.
Also, I've wired up GraphViz for generating pretty pictures from the  
state information:

Does Fedora include the dot executable normally?
