Adds a tabular view of the topology data

The traditional network engineer workflow includes a diagram, a
spreadsheet, and the CLI.  This adds an experimental view of the
network topology data in a spreadsheet like table view.

* Adds angular-xeditable dependency for tables view.
* Add data binding models
* Add message transformations from table to topology formats
* Adding dependencies for tables view
