Overview
========

The :mod:`phylozoo.core.quartet` module provides data structures for working with
quartets, which are four-taxon unrooted trees that serve as building blocks for
many concepts in phylogenetic analysis.

All classes and functions on this page can be imported from the core quartet module:

.. code-block:: python

   from phylozoo.core.quartet import *
   # or directly
   from phylozoo.core.quartet import Quartet, QuartetProfile, QuartetProfileSet
