BUG: fixed typo in read_cfradial functions
+Add locations of all well-known WSR-88D stations. (Source: Weather Climate Toolkit)
+Add capability to read old nexrad-cdm archive. (Read lat,lon,alt from config)
*It is more reasonalbe to always set reference altitude to sea surface when mering multiple radars. (Change in grid_mapper.py)
BUG: fixed bug in add_field_like radar method

add_field_like method of radar would overwrite the old field's data and
metadata since a copy was not made, this correct this behavior.
ENH: 4DD routine

Adding the capability to use a previous velocity volume as an initial condition
to the dealiasing routine. Note that this enhancement was how the original 4DD
algorithm was intended to be implemented, as it should provide better results.
This commit attempts to address some of the issues raised in issue #119.
ADD: Cython generated _fourdd_interface.c

Adding the generated C file from the Cython build since Cython isn't
a build dependency of Py-ART.
FIX: Ensuring proj matches basemap
ENH: Added point plotting on maps
FIX: A couple of bugs with the first commit
ENH: range line segment plotting and range rings on radar maps
FIX: Minor typos and bugs
MOD: _fourdd_h.pxd

Attempting to expose some of the defined constants in the header file
FourDD.h so that the user knows what the values of some of these
constants are at compile-time. As with discussion with @jjhelmus, these
constants cannot actually be changed at run-time; they must be changed
before compiling.
Added an example for basemap plotting
BUG: Fixed label offset
ENH: default configuration

Adding wind retrieval fields to the default configuration file. The bare
bones metadata for these fields are included: 'units', 'standard_name',
and 'long_name'.
ENH: location set when reading old NEXRAD files.

Reading CDM converted NEXRAD files which do not contain the
latitude, longitude and altitude will not fill these parameters
in from the known locations of the NEXRAD stations.

ENH: Location determined when reading older NEXRAD files
Merge pull request #136 from kirknorth/master

ENH: default configuration
Merge remote-tracking branch 'arm_doe/master'
STY: remove trailing whitespace in default_config.py
