Title: Allow nodes and edges to be dragged in interactive demo (#27)

I've added the interaction, but I've left room for improvements.

Also:
* Added dagre.layout.graph(), which returns the current graph (it's useful for managing nodes and edges)
* Set dagre.layout.run() chainable
* dagre.layout.init() saves the edge id. for later using it inside SVG elements (to handle them properly)
* Added some comments to dagre.graph methods
