/**
* This class represents a handler for a type of song event.
* It is used by the ScriptedSongEvent class to handle user-defined events.
*
* Example: Focus on Boyfriend:
* ```
* {
* "e": "FocusCamera",
* "v": {
* "char": 0,
* }
* }
* ```
*
* Example: Focus on 10px above Girlfriend:
* ```
* {
* "e": "FocusCamera",
* "v": {
* "char": 2,
* "y": -10,
* }
* }
* ```
*
* Example: Focus on (100, 100):
* ```
* {
* "e": "FocusCamera",
* "v": {
* "char": -1,
* "x": 100,
* "y": 100,
* }
* }
