FieldList.select_by_ncvars throws an error #76
Description
I get the following error (using cf-python 3.4.0) when trying to use FieldList.select_by_ncvars to select a field by netCDF variable name:
In [1]: import cf
In [2]: fl = cf.read('ESACCI-OC-L3S-IOP-MERGED-5D_DAILY_4km_GEO_PML_OCx_QAA-20010101-fv4.2.nc')
In [3]: fl.select_by_ncvar('atot_412')

I tried this too:
In [6]: fl.select_by_ncvar(ncvars='atot_412')
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)

TypeError: select_by_ncvar() got an unexpected keyword argument 'ncvars'
Please would you be able to help?
