InputHandler

A utility class that provides a quick user-input handling functionality. It supports mouse interactions with world items, with default mouse-particle interactions baked in. Moreover, it also has key-event listening (can be on a focusable element, or the whole window). Lastly, it can handle simultaneous mouse-key press combinations.

Note: This will only work with an HTML canvas element in the browser.
