Unity - Adding commands to component context/cog menu.

AssignSceneName

// Unity Version: 3.5.7+

// This script demonstrates how you can use MenuItem to append commands to a script component context menu.
// The new commands will be available by right-clicking on a component header or clicking the little cog icon.
// Docs: http://docs.unity3d.com/ScriptReference/MenuItem.html

// Note: You must use the current class name/type in both the MenuItem and where the context is used in the code.
