/**
 * <h3>A High Dynamic Range (HDR) Histogram that uses a packed internal representation</h3>
 * <p>
 * {@link PackedHistogram} supports the recording and analyzing sampled data value counts across a configurable
 * integer value range with configurable value precision within the range. Value precision is expressed as the
 * number of significant digits in the value recording, and provides control over value quantization behavior
 * across the value range and the subsequent value resolution at any given level.
 * <p>
 * {@link PackedHistogram} tracks value counts in a packed internal representation optimized
 * for typical histogram recoded values are sparse in the value range and tend to be incremented in small unit counts.
 * This packed representation tends to require significantly smaller amounts of stoarge when compared to unpacked
 * representations, but can incur additional recording cost due to resizing and repacking operations that may
 * occur as previously unrecorded values are encountered.
 * <p>
 * For example, a {@link PackedHistogram} could be configured to track the counts of observed integer values between 0 and
 * 3,600,000,000,000 while maintaining a value precision of 3 significant digits across that range. Value quantization
 * within the range will thus be no larger than 1/1,000th (or 0.1%) of any value. This example Histogram could
 * be used to track and analyze the counts of observed response times ranging between 1 nanosecond and 1 hour
 * in magnitude, while maintaining a value resolution of 1 microsecond up to 1 millisecond, a resolution of
 * 1 millisecond (or better) up to one second, and a resolution of 1 second (or better) up to 1,000 seconds. At its
 * maximum tracked value (1 hour), it would still maintain a resolution of 3.6 seconds (or better).
 * <p>
 * Auto-resizing: When constructed with no specified value range range (or when auto-resize is turned on with {@link
 * Histogram#setAutoResize}) a {@link PackedHistogram} will auto-resize its dynamic range to include recorded values as
 * they are encountered. Note that recording calls that cause auto-resizing may take longer to execute, as resizing
 * incurs allocation and copying of internal data structures.
 * <p>
