Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(name, *args) ⇒ Object

Calling the Ruby method executes a subcommand with the same name. Since the Ruby methods are called first, care must be taken to avoid name collisions. For example, subcommands such as call need to be redefined.
