storm vortex tracks (ATCF)
--------------------------

This module provides functionality to

1. extract an ATCF best track dataset (``fort.22``)
2. randomly perturb different parameters (intensity, size, track coordinates) to generate an ensemble of tracks
3. write out each ensemble member to the ATCF tropical cyclone vortex file (``fort.22``)
