Component Types
There are two types of two-way-rest components: Getters and Mutaters. Getters retrieve instances, and Mutaters mutate instances. Getters include index and show components, and Mutaters are create, update, and destroy.
Every component sends an instance of itself to the props.instance(s) of its children, however while Getters send the actual instance, Posters send a substate instance if it exists. (Substate instances are created on errors or successes )
