A very small python library for implementing basic Entity-Component-System (ECS) structures.
The main structure of the library is the Registry, with which you can create entities, and attach
components onto them.
The library additionally provides an interface for systems ISystem, and some basic components, such as an EventEmitter and a base class for Events. Furthermore, it provides a simple structure that implements an applications entry-point, and uses imgui for creating GUIs.
