This is a request based on the fact that a shading language may not allow for initialization of a uniform
as part of the declaration. It is also useful for code reuse if the shader code itself is used to determine uniqueness for
reuse (say to to avoid shader recompilation)

The proposal is to add in a generation option settable can be set before generation is requested. It would apply to all generators, including OSL and MDL. Here it would be a main function argument initialization option.

Simplifications to editor headers (#1239)
081e7e5 
This changelist simplifies the header files in MaterialXGraphEditor, with no changes to editor logic or behavior.

- Remove a bidirectional dependency between Graph.h and UiNode.h, moving the UiEdge class class from Graph.h to UiNode.h.
- Move include directives from headers to source code where possible.
- Remove unused include directives where possible.
