* histogram aggregator draft
* add tests for buckets
* naming stuffs
* docs
* add tests for buckets
* fix doc
* update year
* adds docs for Histogram
* docs for boundaries.
* addresses review comments
Change to less-than buckets. Add offset checks. Unexport fields that don't need to be exported. Fix tests when running on profile with int64 number kind.
* sort boundaries
* remove testing field
* fixes import order
* remove print 🙈
Rename the package from "export" to "metric". Note that all the existing
imports of this package use an explicit name of `export` and, therefore,
no import declaration changes are included.
Rename the `MetricKind` to `Kind` to not stutter in the type usage. Note
this does not include a method name change for the `Descriptor` method
`MetricKind`.
This import package doesn't match the tests file, preventing imports of
the project from master with tests (without go modules).
The package path matches the test file version, so this moves
aggregator.go to match too.
Change all occurrences of value to pointer receivers
Add meta sys files to .gitignore
Code cleanup e.g.
- Don't capitalize error statements
- Fix ignored errors
- Fix ambiguous variable naming
- Remove unnecessary type casting
- Use named params

So it's explicit they are for spans, and we reduce the risk of name
conflict
* remove not moot todo
* rename sdk exporter to export
* only execute the SpanData if it is sampled
