                                           CSVGrammar

A grammar that uses python's csv module to parse files.

Note that these grammars by default interpret the first line of the input file as the column names. When your files don't follow that convention, you *must* give names (as in ``names='raj2000, dej2000, magV'``), or you'll lose the first line and have silly column names.

CSVGrammars currently do not support non-ASCII inputs. Contact the authors if you need that.

If data is left after filling the defind keys, it is available under the NOTASSIGNED key.
