Minor Documentation Update

This small patch release just contains documentation (written and example tests) updates.

Attempt Number Accuracy

This is really a bug-fix, but it technically breaks backwards compatibility, so I'd rather be safe than sorry here.

tl;dr: retry.Action functions attempt numbers were 1-too-low and strategy.Limit was allowing 1-too-many attempts.

For more details, see #12.
