7d301220a2 Automate getting the list of examples to build (and switch to go 1.13 to avoid module problems) (#246)
* automate building all the examples

the EXAMPLES variable was out of date - the stackdriver example wasn't
even built

let's automate it, so we don't need to remember about updating the
variable after adding a new example to the examples directory

* move jaeger example to example directory

this should be in the examples directory, so it can be built by the
make test during CI.

* switch to go 1.13

circle ci uses go 1.12 (which is the oldest 1.12 release) that
contains some bugs with module handling

let's switch to go 1.13.3, the latest go currently

* use a single valid revision of the project in go.mod files

this probably shouldn't be a problem since the switch to go 1.13 in
circle ci, but cleans up the mess and the use of bogus releases

9ed97980e2 Add Stackdriver Trace exporter for trace. (#160)
* Add Stackdriver Trace exporter for trace.

TODOs for future work is:

* to replace bundler.Bundler

* to add proper tests for the exporter

passing option struct directly.
This fix is aliging the same fix for Jaeger (#146, #161)

* Change Option struct to be function type

* Change the original Option struct to be private

unregistered.

339ca2d974 Initial opentracing bridge (#98)
* Allow specifying custom timestamps for events

Adding event with timestamp is not yet a part of the OpenTelemetry
specification, but this function will come in handy when implementing
the OpenTracing bridge.

* Add opentracing bridge, wrapper tracer and migration interfaces

There are some features missing - setting up links and span kind;
context propagation will only work between two OpenTracing bridges.

* Add some tests for the opentracing bridge

The tests mostly check various aspects of the cooperation between
OpenTracing and OpenTelemetry APIs.

a776e95c61 Consolidate AddEvent and Event methods, add FinishOptions (#99)
* Merge two event methods in span API

There was an agreement to get rid of the Event interface and
consolidate the two methods for adding events into one. See #57.

* Eliminate the use of the Event interface

There is no need for the SDK to provide the implementation of the
Event interface - it is used nowhere.

* Drop the Event interface

It's dead code now.

* Make it possible to override a finish timestamp through options

Opentracing to opentelemetry bridge will certainly use this feature.

* Obey the start time option

* Add tests for events and custom start/end times
