* All IDs for DOT objects, including names, options, and values, are
now automatically quoted as necessary for graphviz. Labels are
handled specially in order to account for \l, \r, and \n sequences
but are otherwise treated the same as other options. Some changes
were made in order to remove explicit quotes from labels which are
no longer necessary.
* Removed backwards compatability method inject.
* DOTSimpleElement provides no useful function, so remove it
* Add support for the Mrecord shape to DOTNode. Rewrite DOTNode#to_s
to be easier to understand. #Rewrite DOTPort to allow for nesting
ports.
* DOTElement no longer sets the label unless the user explicitly sets
one.
* Subgraphs must be identified by a "subgraph" header rather than a
"graph" header
* Added equality test for graphs, added cycle locating. Modified
initialize to allow duplicating and merging of graphs.
* Assorted bug fixes.
