"""
Progressively call the command that was given in argument. Used
when `yield` is present in the Command's `func()` method.
Args:
cmd (Command): the command itself.
generator (GeneratorType): the generator describing the processing.
reponse (str, optional): the response to send to the generator.
Raises:
ValueError: If the func call yields something not identifiable as a
time-delay or a string prompt.
Note:
This function is responsible for executing the command, if
the func() method contains 'yield' instructions. The yielded
value will be accessible at each step and will affect the
process. If the value is a number, just delay the execution
of the command. If it's a string, wait for the user input.
