/**
 * A packed-value, sparse array context used for storing 64 bit signed values.
 *
 * An array context is optimised for tracking sparsely set (as in mostly zeros) values that tend to not make
 * use pof the full 64 bit value range even when they are non-zero. The array context's internal representation
 * is such that the packed value at each virtual array index may be represented by 0-8 bytes of actual storage.
 *
 * An array context encodes the packed values in 8 "set trees" with each set tree representing one byte of the
 * packed value at the virtual index in question. The {@link #getPackedIndex(int, int, boolean)} method is used
 * to look up the byte-index corresponding to the given (set tree) value byte of the given virtual index, and can
 * be used to add entries to represent that byte as needed. As a succesful {@link #getPackedIndex(int, int, boolean)}
 * may require a resizing of the array, it can throw a {@link ResizeException} to indicate that the requested
 * packed index cannot be found or added without a resize of the physical storage.
 *
