* 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
