This is something I needed; maybe it will be of use to others. `Dates` uses the type `CompoundPeriod` to handle additive combinations of distinct time `Period`s (like `Day(5) + Minute(25)`).

I have made the type iterable, indexible, more robust and added plural period names as a way to get the total number of, say, whole seconds (including Minutes etc.) that a time value holds.

The [README](https://github.com/JeffreySarnoff/CompoundPeriods.jl/blob/master/README.md) shows how it may be useful.
