Add a fan out and merge nodes

[JohannesKlauss]

Great editor!
One thing I am missing would be a fan out and merge node for vectors (i.e. fanning out a vec4 into x, y, z, w and vice versa). Would you be interested in a PR for that?

All in all, are you planning to build more complex nodes, like color ramps, etc.? One thing I often find lacking is the availability of more complex nodes like in blender, which makes using visual shading editors pretty hard.

Yeah the component splitting node would be cool (and color ramp and similar nodes like in blender). Right now I'm working on cleaning up and about to upload the logical nodes (functions, if/else etc) so wait for that before touching the code because I had to do a mayor refactoring. In the version I'm about to upload a do implemented the swizzle node at least...

The idea is to make this something build by the community. All PR are welcome and that's the entire goal of how this repo should evolve.

PS: sorry for the delay in response I didn't saw any notification of this PR on my email, I thought github would send me one.

just uploaded the latest code with the logical nodes, ifs, etc... you can now work with the code. In the src/nodes folders I created a template file to use as base for new nodes but you can obviously just see how the current ones are made to get a better feel for them.
