RavenDB Counters & Time series chapter is ready for review

I’ve started the work to update the Inside RavenDB book to version 5.0, covering all the new things that happened in RavenDB since the 4.0 release.

I have just completed a major milestone, I finished the chapter discussing time series and counters, and I would really appreciate any comments you have to make.

You can find the new chapter here, look at Chapter 5, I removed all the rest.

Please let me know what you think.
