0.2.0-rc3

This release provides all functionality for the 0.2.0 release. One can use counters for success, failure or count totals. One can also measure response times as well as response sizes in both histogram and summary form.

This release also fixes a few bugs, which are now being held in the CHANGELOG.md file.

Use the "original-" jar if you want to just use this source code and you want to download the related io.prometheus jars separately.
