Version 0.1.3

This version adds many new features including:

• The lat_range, lon_range, min_brightness, max_brightness and brightness_freq_range keywords to the SkyModel.select method.
• The SkyModel.assign_to_healpix method to assign point component objects to a healpix grid (using the nearest neighbor approach).
• The nan_handling keyword to the SkyModel.at_frequencies method to control how NaNs in the stokes array on subband objects are handled during interpolation.
• The SkyModel.calculate_rise_set_lsts and the SkyModel. cut_nonrising methods.

Also, the ra and dec are no longer required parameters on healpix objects (since that information is encoded in the hpx_inds parameter). The new SkyModel.get_lon_lat method can be used to get the lat/lon values for any sky type (calculated from the hpx_inds parameter on healpix type skies).

Full changes detailed below and in our changelog:
