patch to HTML::FormValidator available

[markjugg]

I have now prepared a patch to the code and POD of HTML::FormValidator with the following changes. I would appreciate your review and feedback of these changes. The patched module can be downloaded here:

http://mark.stosberg.com/tech/perl/form-validation/FormValidator.pm

Changes:

• Several updates to the syntax and grammar of the POD
• Added code and documentation for a procedural interface
• Added code and docs to allow specifying single item anon. arrays as regular strings
• Added initial code to support better handling of dynamic form validation. This included added two new routines: constraint_suffix_map and constraint_prefix_map. This allows you map all fields that have a common ending to automatically have a particular constraint applied (for example, validating all fields ending in _zip as zipcodes)
• added option for "dependency groups"-- when any field in the group is field in, they all become required.

I have tested all my changes, but I would appreciate your reality checks as well.

I have a few more features I'd like to add to round out support for dynamic form field generation, but I thought it would be good to send this version out for review already. Here are the features I want to add:

require_suffixes
optional_suffixes
require_prefixes
optional_prefixes
require_regex
optional_regex

The basic idea to specific whether some fields are required or optional based on there suffix, prefix, or a regular expression.
