Variable tooltips, domponent docs, and contextually hidden variables.

Variable Tooltips
On any public variable of a MonoBehaviour component, you can add tooltips that developers will be able to see from the Unity inspector.

Component Docs
Placing the [MonoDoc] attribute above a MonoBehaviour class will allow you to store a few instructions on how a component should be used. These instructions will be visible in the Unity inspector.

Contextually Hidden Variables
You can show and hide variables based on an enum context. This allows for much cleaner and more organized components.
