+	the mouse cursor at the same time. This uses a stack approach similar to how
+	ContextActionService works. The most recent override takes precedence, and any
+	previously set overrides will remain on the stack beneath it until removed.

+	Example usage:
+		MouseIconOverrideService.push("PurchasePrompt", Enum.OverrideMouseIconBehavior.ForceShow)
+		MouseIconOverrideService.pop("PurchasePrompt")
