great, thanks! this could be very useful to me.

Two comments:

missing : string, optional
         A string representing a missing value, irrespective of the 
column where it appears (e.g., ``'missing'`` or ``'unused'``.

It might be nice if "missing" could be a sequence of strings, if there 
is more than one value for missing values, that are not clearly mapped 
to a particular field.

missing_values : {None, dictionary}, optional
         A dictionary mapping a column number to a string indicating 
whether the corresponding field should be masked.

would it possible to specify column header, rather than number here?
