Figure out a better name for NoiseModule

No description provided.

Suggested Names:

• Module
• NoiseModule (I prefer this, obviously)
• ModuleBase
• ValueSource ( I don't like this one because not all of the noisemodules will be sourcing values, most will be either modifying the value or modifying the point.)

• NoiseGen
• NoiseFn
• GenFn

In the future I see that these structs could simply implement Fn(Input) -> Output, but we need to wait for these to be stabilized first.

I also think that we need an impl for Fn.

Based off of the synonyms for module, here are other potential names:

• NoiseComponent
