Description: # Kozai
        
        Kozai is a Python package to evolve hierarchical triples in the secular
        approximation.  Hierarchical triples may be evolved either using the
        Delaunay formalism (Naoz et al. 2013b) or the vectorial formalism (Katz et
        al. 2011).  The quadrupole, octupole, and hexadecapole terms of the
        Hamiltonian may be toggled to be included (or not) in the equations of
        motion.  Post-Newtonian terms may also be toggled to include both
        relativistic precession (PN 1) and gravitational radiation (PN 2.5) using
        terms from Blaes et al. (2002). 
        
        The package provides a TripleDelaunay object which may be integrated using
        the Delaunay orbital elements and a TripleVectorial which may be integrated
        using the eccentricity and angular momentum vectors.  This allows the
        integration to occur within the context of an external Python program.
        
        The underlying integrator is from the SciPy ODE package.  By default this
        package uses VODE as its integration algorithm, but the algorithm may be
        changed to any of the other integration algorithms supported by the SciPy
        ODE package.
        
        ## Installation
        
        The Kozai package is available on PyPI and can be installed with pip:
        
        ```
        pip install kozai
        ```
        
        Or, if you do not have the permissions to run the above:
        
        ```
        pip install --user kozai
        ```
