'Generator which yields up to `count` recurrences after the given
datetime instance, equivalent to `after`.
:param dt:
The datetime at which to start generating recurrences.
:param count:
The maximum number of recurrences to generate. If `None` (default),
dates are generated until the recurrence rule is exhausted.
:param inc:
If `dt` is an instance of the rule and `inc` is `True`, it is
included in the output.
:yields: Yields a sequence of `datetime` objects.'
