Add PhysicallyBased node definition (#27)

* First pass to create valid nodedef.

* Some fixes for vec arrays. Note floatarray makes code gen fault so use string for now.
Add all examples as instances.
Validated and test in node editor.

* Fix up lists for strings on instances
Load into MXlab editor and snapshot.

* Update API docs.
