* Add MetricAggregator.Merge() implementations * Update from feedback * Type * Ckpt * Ckpt * Add push controller * Ckpt * Add aggregator interfaces, stdout encoder * Modify basic main.go * Main is working * Batch stdout output * Sum udpate * Rename stdout * Add stateless/stateful Batcher options * Undo a for-loop in the example, remove a done TODO * Update imports * Add note * Rename defaultkeys * Support variable label encoder to speed OpenMetrics/Statsd export * Lint * Checkpoint * Checkpoint * Doc * Precommit/lint * Simplify Aggregator API * Record->Identifier * Remove export.Record a.k.a. Identifier * Checkpoint * Propagate errors to the SDK, remove a bunch of 'TODO warn' * Checkpoint * Introduce export.Labels * Comments in export/metric.go * Comment * More merge * More doc * Complete example * Lint fixes * Add a testable example * Lint * Dogstats * Let Export return an error * Checkpoint * add a basic stdout exporter test * Add measure test; fix aggregator APIs * Use JSON numbers, not strings * Test stdout exporter error * Add a test for the call to RangeTest * Add error handler API to improve correctness test; return errors from RecordOne * Undo the previous -- do not expose errors * Add simple selector variations, test * Repair examples * Test push controller error handling * Add SDK label encoder tests * Add a defaultkeys batcher test * Add an ungrouped batcher test * Lint new tests * Respond to krnowak's feedback * Checkpoint * Funciontal example using unixgram * Tidy the example * Add a packet-split test * More tests * Undo comment * Use concrete receivers for export records and labels, since the constructors return structs not pointers * Bug fix for stateful batchers; clone an aggregator for long term storage * Remove TODO addressed in #318 * Add errors to all aggregator interfaces * Handle ErrNoLastValue case in stdout exporter * Move aggregator API into sdk/export/metric/aggregator * Update all aggregator exported-method comments * Document the aggregator APIs * More aggregator comments * Add multiple updates to the ungrouped test * Fixes for feedback from Gustavo and Liz * Producer->CheckpointSet; add FinishedCollection * Process takes an export.Record * ReadCheckpoint->CheckpointSet * EncodeLabels->Encode * Format a better inconsistent type error; add more aggregator API tests * More RangeTest test coverage * Make benbjohnson/clock a test-only dependency * Handle ErrNoLastValue in stress_test * Update comments; use a pipe vs a unix socket in the example test * Update test * Spelling * Typo fix * Rename DefaultLabelEncoder to NewDefaultLabelEncoder for clarity * Rename DefaultLabelEncoder to NewDefaultLabelEncoder for clarity * Test different adapters; add ForceEncode to statsd label encoder
