# ITaskDefinitionExtension

An extension for Task Definitions.

Classes that want to make changes to a TaskDefinition (such as
adding helper containers) can implement this interface, and can
then be "added" to a TaskDefinition like so:

   taskDefinition.addExtension(new MyExtension("some_parameter"));
