be8fb0b4e2 Golang metrics prototype (#100)
* initial metrics work

* rename cumulative to counter

* rename bidirectional to nonmonotonic

* rename unidirectional to monotonic

* rename nonnegative to signed

this changes the default semantics a bit - before the change measure
could record negative values by default, now it can't.

The specification draft currently specifies both NonNegative and
Signed, but I think it's a mistake.

* rename instrument to descriptor

* license

* rework measurement values

* make measurement value a tagged union

* simplify to one kind of metrics

* add observers

* change some interfaces to match the spec

* keep integral measurement separate from floating ones

* remove duplicated measurement type

* add checking for options

* reorder some fields and functions

* rename a function

to avoid confusion between the Handle type and the Measure type

* drop disabled field from descriptor

* add back typed API for metrics

* make metric options type safe

* merge alternatives into a single bool

* make value kind name less stuttery

* fix observation callback prototype

* drop context parameter from NewHandle

* drop useless parameter names

* make descriptor an opaque struct

* use a store helper

* handle comment fixes

* reword Alternate comment

* drop the "any value" metrics

* make measurement value simpler

* document value stuff

* add tests for values

* docs

* do not panic if there is no span ID in the event

3362421c9b Drop the registry package (#130)
This is to shrink the PR #100.

The only place where the registry.Variable type was used was metrics,
so just inline that type into its only user. The use of the
registry.Variable type in core.Key was limited to the Name field.

The stats package also used the registry.Variable type, but seems that
also only the Name field was used and the package is going to be
dropped anyway.

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

541621cff0 Move basic example into its own subdirectory (#25)
This makes it more obvious (without having to look at the code) that
the basic example is actually an example, rather than something tied to
the other examples or some sort of metadata file.
