Zipkin exporter (#495)
* Add zipkin exporter The zipkin exporter implements the SpanBatcher interface. It follows the current-at-the-time-of-writing document about conversion from OpenTelemetry span data to Zipkin spans. Which means that endpoint information is not yet filled. * Fix typo in docs * Add a zipkin example This sends span information to a locally running zipkin collector. Currently I have a problem getting the collector to show me the spans after accepting them with HTTP 202. Not sure if this is because of missing endpoint information. * Make gitignore consistent The fixed paths should be prefixed with a slash. The "relative" paths mean that git will ignore all the files that end with the path. * Add tests for zipkin exporter
