macro_command.rb

A MacroCommand maintains an list of Command Class references called SubCommands

When execute is called, the MacroCommand instantiates and calls execute on each of its SubCommands.Each SubCommand will be passed a reference to the original Notification that was passed to the MacroCommand‘s execute method.

Unlike SimpleCommand, your subclass should not override execute, but instead, should override the initialize_macro_command method, calling add_sub_command once for each SubCommand to be executed.
