SceneView Context Menu script. (Free!)

Gist file.
No setup required.
Shift + Right click on an object in the scene to bring up a list of it's methods marked with [ContextMenu].



Features:
- No set up. Automatically grabs [ContextMenu] of hoverd items.
- No colliders needed. Uses the built in HandleUtility.PickGameObject.
- Shows custom context menus for internal classes like Transform.
- Implements GameObject/Create menu, so you can create objects at mouse click position.
- Menus for selecting/deselecting GameObjects based on component type or name.
- Menus for snapping selected objects to the floor/terrain.

Warnings:
- Undo isn't really supported.
- Context menus marked with [MenuItem("CONTEXT/")] might not work, as I don't know how to pass a target reference to them through EditorApplication.ExecuteMenuItem(command).

GetContextMenus()
Add a GetContextMenus() method to any component to have it return context menu items. It can return either: ContextItem[], List<ContextItem>, ContextMenuBuilder, or a MonoBehaviour. If it returns a MonoBehaviour, that object will have GetContextMenus called on it instead, useful as a global or parent context object.
It can also accept a Ray as a parameter. This will be the ray cast by the scene camera on click, useful for returning context specific menus.

[SceneViewContextMenu]
Add the [SceneViewContextMenu] attribute above any component method and it will be treated as if it were marked [ContextMenu], only Unity won't display it in the component context menu, and it better supports submenus, as the Unity ContextMenu doesn't seem to let you use /.

ContextMenuBuilder
A GetContextMenus method can return one of these. It's just a neater, simpler way of creating menus.

ContextMenuBuilder GetContextMenus(Ray ray)

{

    return new ContextMenuBuilder()

        .Item("Reset State", Reset)

        .Item("Set State to On", SetState, State.On)

        .Item("Set State to Off", SetState, State.Off)

        .Seperator()

        .Item("Cast Ray", () => CastRay(ray));

}

Here's an example of how I've used it.
