Declared in `<balm_metricsample.h>`

Create an empty sample group. By default, the `records()` address is 0, `numRecords()` is 0, and the `elapsedTime()` is the default‐ constructed `bsls::TimeInterval`.

Create a sample group containing the specified sequence of `records` of specified length `numRecords`, recorded over a period whose duration is the specified `elapsedTime`. The behavior is undefined unless `0 <= numRecords` and `records` points to a contiguous sequence of (at least) `numRecords` metric records. Note that the contents of `records` is _not_ copied and the supplied array must remain valid for the productive lifetime of this object or until the records are set to a different sequence by calling the `setRecords` manipulator.
