# Instead of having to figure out how many steps or how many epochs I want to wait,
# (e.g. `if epochs % viz_every == 0:` or `if steps % ckpt_every == 0`)
# sometimes I'd rather have something wall-clock-time-based and easy to call. 
# Hence this. 
# Sample usage:  `if do_every('15min'):`, or with optional id: `if do_every('1h', 'viz'):`  etc.
