	{devil's advocate}: Maybe it's time to expand the CSV module... Of
course, if we set it to recognize x1E as a record separator, we should
be fair and also incorporate the other two ASCII "separator" codes. 

	x1D (group separator) could be used to signal a "new table" -- ie; a
change in record structure (number of columns, header labels). And then
x1C (file separator) could represent a new "worksheet" (in Excel terms).

	We'd need some sort of flag/query method to detect these changes, of
course.

	while not csv.EndOfSheet():
		while not csv.EndOfTable():
			...

	And then there is the potential of using <VT> and <FF> as
equivalents for x1D and x1C (for those files using <TAB> and <CR><LF> as
field/record separators).
