PYTHON. Added possibility to call for variable <<-v enfact>> - enrichment factor - given that you have co2, ap, bp and ps fields in your file. This will give you the enrichment factor of non condensible gases, ranging from 0 (no enrichment) to X (enrichment by a factor X compared to the mean non condensible gases mass mixing ratio (which is also computed for the relevant time step)).

5	### A. Spiga -- LMD -- 06~09/2011 -- General building and mapping capabilities
6	### T. Navarro -- LMD -- 10~11/2011 -- Improved use for GCM and added sections + 1Dplot capabilities
7	### A. Colaitis -- LMD -- 11/2011 -- Mostly minor improvements and inter-plot operation capabilities + zrecast interpolation for gcm
8	### A. Spiga -- LMD -- 11~12/2011 -- Extended multivar subplot capabilities + cosmetic changes + general cleaning and tests
9	### A. Colaitis -- LMD -- 12/2011 -- Added movie capability [mencoder must be installed]
10	### A. Spiga -- LMD -- 12/2011 -- Added HTML animated page capability + general tests of consistency [winds, etc...] + consistent generic movie loop
11	### J. Leconte -- LMD -- 02/2012 -- Added area weighted averaging. Compatibility with terrestrial gcm.
12	### A. Spiga -- LMD -- 03/2012 -- Cleaning and improved comments
