Prepare for version 0.6

[dilawar]

It is a major rewrite. Major changes are

• Removed pop and remove apis.
• As soon as a data point is pushed, the statistics are computed.
• Most fields are private.
• Rely on watermill crate for underlying computations. It is much better tested.
• Changes to new, default and with_fixed_capacity APIs.
• Underlying Vec is replaced by VecDeque

@dilawar I was wondering about a more meta issue -- if we are using watermill for all the computations, does that not invalidate the reason of existence of SimpleAccumulator as a public github repo, since we have not added any novelty?

Yes. I haven't added anything new except an easier API. This is more tested and I can use it today and move on to unsolved problems. We can re-invent the wheel later (but why?). I'll still have to add more computations #23 etc.
