Simplification for adding or removing CLaMS parameters

As it is written now, the chemical species or parameters in the CLaMS output are repeated seven times for

defining the data_organisation table in class CLAMSDataAccess
define the Netcdf variables used in CFVariableIdentifier
define the default value range in horizontal and vertical plots
create the classes "HS_ChemStyle_PL_xxx" and "VS_ChemStyle_PL_xxx"

It would be easier to read these from one location with the syntax like

clams_config = {
 u'CO': {'levels': {50: (0., 20),
                    500: (0, 200.0)},
         'limits': (0., 200.),
         'units': u'ppbv',
         'cfidentifier': 'CO_volume_mixing_ratio',
         'long_name': 'CO_volume_mixing_ratio',
    }
...
}

This construct should be known everywhere the loops over the CLaMS species are needed. It should rather be a configuration file than a python programme. With this it should be very easy to add or remove chemical parameters.

Potentially the information besides the limits/levels could be also derived from the NetCDF files this would make it even easier to add/remove parameters.
