New symbol

Hi Mr.Adrai, Great work on the flowcharts.

Few questions :

1) I am trying to add a symbol that supports icons in it - Are there any guides/pointers to how I can do this - icons / text in each box as available [here](http://www.conceptdraw.com/How-To-Guide/picture/swim-lane-flowchart-symbols/RapidDraw-and-Action.png)

2) Do you think flowchart.js can support swimlanes like in the above image.

3) I am unable to get the hot-edit working during development. webpack says its rebuilt, but changes are not reflecting. I am building and restarting the devserver for every code change, can you please guide in getting this live reload working.

Many thanks.
