Network Graph - setData should update only the changed Data

[jeffersonswartz]

Expected behaviour

The Data should only update the changed data

In line chart if we update the data it will just change the data rather than re-rendering the whole chart. Example: http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/members/series-setdata/

Actual behaviour

The whole network chart is re-rendered
