To retrieve the data traveling through a link you can call node.getInputData or node.getOutputData
### Define your Graph Node
When creating a class for a graph node here are some useful points:
- The constructor should create the default inputs and outputs (use ```addInput``` and ```addOutput```)
- Properties that can be edited are stored in ```this.properties = {};```
- the ```onExecute``` is the method that will be called when the graph is executed
- you can catch if a property was changed defining a ```onPropertyChanged```
- you must register your node using ```LiteGraph.registerNodeType("type/name", MyGraphNodeClass );```
- you can alter the default priority of execution by defining the ```MyGraphNodeClass.priority``` (default is 0)
- you can overwrite how the node is rendered using the ```onDrawBackground``` and ```onDrawForeground```
