PyLoT: Main program
===================
PyLoT is a seismic data processing software capable of picking seismic
phases (symmetric and asymmetric error assignment), exporting these to
several common phase data formats and post process the data, e.g. locating
events, via external localization software.
Additionally PyLoT is meant as an interface to autoPyLoT which can
automatically pick seismic phases, if the parameters have properly been
chosen for the particular data set.
