* Use react-grid-layout instead of gridster
* visualizations show and resize
* display slice name and description; links work
* positioning of widgets to match gridster, rowHeight matches
* Change margins, rowHeight, unpositioned viz, and expandedSlices to match gridster
* Saving dashboard, deleting slices, formatting on slices (chart control and resize handle), expanded slices fixed.
* responsiveness + use es6 classes
* Minor ui fixes + linting
* CSS transforms on slices messes up nvd3 tooltip positioning.
Turn off CSS transforms for the time being, with a cost of painting speed.
Issue is currently being looked at on the nvd3 repo
