I've made the decision to copy over the NodeGraph API code and NodeEditor code from Base Editor Library to 
this library so that i can make as many changes and enhancements as needed.

Moved the Create New Asset actions from the root of the Asset Browser context menu to "New/Shader"

Added another version of a reroute node that lets you better declutter your graph of noodles going every which way 🍝.

Now you can view all your material parameter, subgraph inputs, and shader features all in one place.

How you usually defined a constant value like float3 for example is to just create an unnamed parameter node and use that. But with the introduction of the blackboard there are now dedicated constant nodes for the following types:

You can now define and use a Radio/Enum shader feature for your graph. And all you need todo is create one in the blackboard and drag it into the graph.

Static Switch node has been replaced with BooleanShaderFeature node.

For now these cannot be defined in subgraphs as I'm not sure how to handle that just yet but that ability todo so should come eventually in a future patch/update.

Just like the regular SceneView in the main editor window. You can now change the ViewMode of the preview viewport. The currently selected mode will even be saved when you save the current shadergraph plus project.
