      public interface ExtensionAware

  Objects that can be extended at runtime with other objects.

       // Extensions are just plain objects, there is no interface/type
       class MyExtension {
         String foo

         MyExtension(String foo) {
           this.foo = foo
         }
       }

       // Add new extensions via the extension container
       project.extensions.create('custom', MyExtension, "bar")
       //                       («name»,   «type»,       «constructor args», …)

       // extensions appear as properties on the target object by the given name
       assert project.custom instanceof MyExtension
       assert project.custom.foo == "bar"

       // also via a namespace method
       project.custom {
         assert foo == "bar"
         foo = "other"
       }
       assert project.custom.foo == "other"

       // Extensions added with the extension container's create method are themselves extensible
       assert project.custom instanceof ExtensionAware
       project.custom.extensions.create("nested", MyExtension, "baz")
       assert project.custom.nested.foo == "baz"

       // All extension aware objects have a special “ext” extension of type ExtraPropertiesExtension
       assert project.hasProperty("myProperty") == false
       project.ext.myProperty = "myValue"

       // Properties added to the “ext” extension are promoted to the owning object
       assert project.myProperty == "myValue"

  Many Gradle objects are extension aware. This includes; projects, tasks, configurations, dependencies etc.
