Small set of utility functions. Currently centered around dynamic programming.

Math.TriangularNumbers provides indexing into upper triangular tables. With back and forth between the index pair and the linear index.

Data.Paired.Vector provided rectangular and upper-triangular pairing of elements from a vector.

Data.Paired.Foldable is a more powerful generalization of such pairing for any foldable container. We try to only retain elements that will be needed for the pairing, while others are being filtered out.

Pipes.Parallel provides some simple tools for parallelisation of tasks with the pipes eco-system.
