%description
Provides a library for generic interval manipulations using a new interval
vector class. Capabilities include: locating various kinds of
relationships between two interval vectors, merging overlaps within a
single interval vector, splitting an interval vector on its overlapping
endpoints, and applying set theoretical operations on interval vectors.
Many of the operations in this package were inspired by James Allen's
interval algebra, Allen (1983) <doi:10.1145/182.358434>.
