See here for custom validators:
http://web2py.com/book/default/chapter/07#Custom-Validators
and here for custom widgets:
http://web2py.com/book/default/chapter/07#Widgets
If your widget returns an INPUT helper, you can assign your custom validator
to the 'requires' argument of INPUT to make it the default for the widget.
However, the book recommends instead associating the validator to the
database field, and then assign requires=field.requires in the widget
definition.
