Added user-defined cmap option to configuration file.
Note, the config.ini file is initialized the first time ragu is run on a computer, so if you've previously run ragu, you'll need to do one of three things to implement this change:
1. add the following two lines directly under the 'param' key
str cmap: Matplotlib colormap to use (default = seismic)
cmap =
2. Regenerate your config file
import os
from ragu import config
get configuration file
basedir = os.path.join(os.path.expanduser('~'),'RAGU')
config.create_config(basedir+'/config.ini')
3. Remove your existing configuration file, and then a new one will be generated upon running ragu
