Segment maps implemented using the FingerTree
type, following
section 4.8 of
- Ralf Hinze and Ross Paterson, "Finger trees: a simple general-purpose data structure", Journal of Functional Programmaxg 16:2 (2006) pp 197-217. http://staff.city.ac.uk/~ross/papers/FingerTree.html
An amortized running time is given for each operation, with n referring to the size of the map. These bounds hold even in a persistent (shared) setting.
Note: Many of these operations have the same names as similar
operations on lists in the Prelude. The ambiguity may be resolved
using either qualification or the hiding
clause.

Segments
A closed segment. The lower bound should be less than or equal to the higher bound.
