When creating your own Classes/Structs/Assets/ect, you'll sometimes want custom editors that pair with them. For example, a Gradient Editor so you can visually see what the Gradient looks like instead of editing the Gradient as if it were a Struct with a list of Colours.

Editor Events are events that are broadcast globally throughout the editor and can be listened to/fired from any Editor Project. These are useful for creating your own custom Editor Tools and making sure they can work in tandem with existing systems.
