// PURPOSE      : Managing user input either via keyboard, mouse movement, clicking, or
//                even mouse wheel. It's currently mostly used for camera traversal,
//                scene switching and exiting the program.
// ===============================
// SPECIAL NOTES: It works by directly calling functions that perform these actions,
// that is it doesn't tell the camera to move by x amount on the next update cycle.
// The input manager goes ahead and does just that. And withing the update calls of each
// object that is affected it deals with the consequences of performing that action.
// ===============================
