RRBVector is a general-purpose, immutable data structure. It provides random access, updates, concatenations, insertions and splits in effectively constant time, as well as amortized constant time append, prepend and local updates. It is backed by a little endian bit-mapped vector trie with a branching factor of 32. Locality is very good, but not contiguous, which is good for very large sequences.
