New Features

Phase Dispersion Minimization as a method to search for periodic
signals in data is now implemented in the stingray.pulse
submodule. To use it, you can use the phase_dispersion_search
function in stingray.pulse.search. The accompanying statistical
tests are located in the stingray.stats module, under
phase_dispersion_probability, phase_dispersion_logprobability
and phase_dispersion_detection_level.
