read "color" code from the properties of a node

[sjz2018]

Please add a functionality so that the color for a node can be rendered with the value from one property of a node such as Node_Color. For example,

labels: {
HostFactor : {
label: 'Note_ID',
color: 'Node_Color' , //this is requested. Node_Color is #654321
// color: '#654321', //this is currently supported
size: 20,
icon: {
name: 'f007',
color: '#FF0',
scale: 1.0
