%%
% Shows the genesis points of each tropical cyclone in the event set. The
% origin points are the points at which the storm peak wind speeds first
% exceed the value of _startv_ as defined in the _params.m_ file, unless that
% value is sufficiently small, in which case the points represent the
% points at which each track was seeded. The tracks may be filtered to
% include only those events whose lifetime maximum winds exceed value
% specified in _params.m_ .
%
% This version of the script uses the free _m_map_ routines, which are
% included with the script set. Various map properties can be set in
% _params.m_ .
