A finger tree is a purely functional data structure designed
to efficiently represent persistent sequences.

It allows amortized constant time access to its elements.
Furthermore concatting (append/prepend) as well as splitting in logarithmic time.

In Fuzion finger trees are used for concatenation of strings and finite Sequences.

The paper introducing the datastructure:
https://www.cs.ox.ac.uk/ralf.hinze/publications/FingerTrees.pdf

The implementation that was used as an inspiration for this port:
