DateTime-Format-Natural 0.93_01

on Perl CPAN

Introduce a class to extract parsable expressions from strings.
[suggested by Colm Dougan]

Add and document the extract_datetime() method.

Test extracting parsable expressions.

Require precision in hour or higher for one token time expressions,
otherwise extracting expressions would be impeded.

Move the formatted string regex to the grammar class;
furthermore, move the according checks to the formatted class.
