Files contain multiple classes/structs

[Sibz]

I.e. https://github.com/Unity-Technologies/EntityComponentSystemSamples/blob/a319c0da6c6a55baadc31c10c8120a28e959766b/UnityPhysicsSamples/Assets/Demos/2.%20Setup/2d.%20Events/2d1.%20Triggers/Scripts/TriggerVolumeForceFieldAuthoring.cs#L50

I was trying to find the system code, looking at the file names I assumed there would only be the Authoring component in there. After giving up and searching else where I found a tutorial that pointed out the systems are in-fact including in the files called *Authoring.

I think for clarity these should be split up.
