Change Log
----------
v1.0.3 Major Changes (10/05/18):
1. Fixed some documentation errors.
2. Removed exception handling on the sounding read, as this was causing more
   debugging issues than it was solving. Now if the sounding read fails the
   program will crash. The resulting trackback will provide guidance to the
   end user on how to resolve the SkewT ingest problem. 

v1.0.2 Major Changes (05/12/16):
1. Added support for band, thresh_dz, and thresh_kdp keywords in the
   blended rainfall algorithm calls. See CSU_RadarTools documentation for
   how these affect the blended rainfall logic. Primary effect is reduced
   use of Zdr at non-S bands.
2. Added support for thresh_zdr keyword (another blended rain breakpoint),
   as well as the ability to adjust parameters in the different blended rain
   equations (e.g., a & b in Z = a * R**b or R = a * Kdp**b). 

v1.0.1 Major Changes (12/08/15):
1. Added std_gates keyword to DualPolRetrieval that allows the user to adjust
   the number of gates used to calculate stddev of diff phase. Default still 11.

v1.0 Major Changes (11/27/15):
1. Made an installable package.
2. Added _FhcVars class to clean up FHC routines.
3. Optimized FHC processing by reducing arrays before making csu_fhc call.
4. Added common sub-module with radar_coords_to_cart function that Py-ART
   just removed.

v0.9 Major Changes (09/25/15):
1. Added QC capabilities, including filters for insects, high SDP, & speckles.
   These are based on the csu_radartools.csu_misc module. QC is performed prior
   to all retrievals, except for KDP calculations.
2. Added kdp_window keyword to DualPolRetrieval, to allow user to vary distance
   for window used in phase filtering and KDP calculation using csu_radartools.
3. Added capability for putting temperature field in radar object.

v0.8 Major Changes (08/07/15):
1. Now supports Python 3.4 and 2.7. Other versions untested.

v0.7 Major Changes (07/02/15):
1. Made code pep8 compliant

v0.6 Major Changes (05/21/15):
1. KDP calculation accepts gate spacing keyword (gs).
2. Adjusted sounding read to work with latest version of skewt
3. More info added to docstrings

v0.5 Major Changes (03/13/15):
1. KDP calculation implemented.
2. Moved keyword arguments to separate dictionary (kwargs) and implemented
   check_kwargs() function to process them.

v0.4 Major Changes (03/05/15):
1. DSD calculations implemented.
2. Project renamed to DualPol from RadBro.

v0.3 Major Changes (02/20/15):
1. Rainfall rate implemented

v0.2 Major Changes (01/27/15):
1. Ice/liquid mass calculations implemented.

v0.1 Functionality(01/26/15):
1. Summer HID calculations implemented.
2. Support for sounding import.
