Unity: Pointable script is missing

[emicre32]

I just started developing using Leap Motion in Unity and I imported a code that uses Pointable class and GestureList class. But I am getting an error saying they were not declared. I couldn't find neither of these classes in the Unity Module I imported.
They are being declared like this:

public static event Action PointableFound = delegate { };
public static event Action PointableUpdated = delegate { };
public static event Action GestureDetected = delegate { };

Does anyone have their source code?

These classes have not been supported for a few years; can you point me to where you saw references for them?
