http.ResponseWriters may implement additional interfaces
(http.CloseNotifier, http.Flusher, http.Hijacker, http.Pusher,
io.ReaderFrom) that get lost when the ResponseWriter is wrapped in
another object. This change uses the httpsnoop package to wrap the
ResponseWriter so that the resulting object implements any of the
optional interfaces that the original ResponseWriter implements as
well as using the replacement ResponseWriter methods that gather
information for tracing.

* Update License header for all source files
- Add Apache 2.0 header to source files that did not have one.
- Update all existing headers dated to 2019 to be 2020
- Remove comma from License header to comply with the Apache 2.0
guidelines.
* Update Copyright notice
Use the standard Copyright notices outlined by the
[CNCF](https://github.com/cncf/foundation/blob/master/copyright-notices.md#copyright-notices)
* 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
