/**
* This package contains an implementation of XDM sequences known as the ZenoSequence.
* A ZenoChain is a list of elements, organized as a sequence of contiguous chunks; it is
* designed to ensure that elements can be efficiently added to either end of the sequence
* without copying the entire sequence, while also leaving the original sequence intact.
* It is thus an implementation of immutable persistent lists optimized for a scenario
* where changes typically occur only at the ends of the sequence.
* The ZenoSequence is a specialization of a ZenoChain for implementing XDM sequences.
