Cycler doesn't cycle

[OceanWolf]

This issue falls mainly along the lines of semantics. I would expect something called Cycler to do the cycling itself, instead it just represents a list, of course we want to create a cycle object from the list, but nothing in "Cycler" actually promotes this...

Perhaps naming this CycleHelper would help, and ooh, just had an idea to combine this with my own cycling experiments... one moment while I make a PR... 😈.

Never mind on that PR, silly idea wanting to create a class ChainedCycle(cycle), wrapper around the CycleHelper but I don't think it would get that much use as the CycleHelper remains recyclable via cycle(CycleHelper), but a ChainedCycle would becomes a one-shot device...

The first version of this did return it's iter wrapped in intertools.cycle, but it ended up being very awkward to work with as most of the time you really want the finite version of the cycle.

Using itertools.cycle is in the first example http://matplotlib.org/cycler/#examples

I was hoping the name would encourage the use of these objects with itertools.cycle

[OceanWolf]

Sure, but a finite version by definition doesn't cycle.

How about a cycling flag? if currently cycling and you switch the flag off it will stop at the end of the next cycle, we could forego itertools.cycle and just use yield...
