discrete helpers

This project provides classes corresponding to concepts in discrete mathematics:

• Binv: binary vector

• Perm: permutation (finite or periodic)

• WalshPerm: Walsh permutation, subclass of Perm (periodic)

• SigPerm: signed permutation, subclass of Perm (finite)

• SetPart: set partition

• SetPartComp: set partition with complement relationship between blocks

• Boolf: Boolean function

Some technical documentation can be found in the doc folder.

The main part of the documentation will be on Wikiversity: Discrete helpers
