Summary: unclear exception text when accessing non existing column

Initial Comment:
ValueError: list.index(x): x not in list

is the standard python exception plus text when looking for an item in a list that does not contain the item.  this exception is raised when you attempt accessing a non existing column.

that 'x' does not really help finding what column you were trying to access, what about this:

    def indexOfFieldName(self, name):
        """Index of field named ``name``."""
        # FIXME: move this to header class
        try:
            return self.header.fields.index(name)
        except ValueError:
            raise ValueError("can't find index of field '%s'" % name)
