IsValid

Validates the incoming value against the given type.

If the type is a range, the value is validated against the range. If the type is a pattern, the value is validated against the pattern. If the type is a date, the value is validated against the date format. If the type is a locale date, the value is validated against the locale date format. If the type is a regular expression, the value is validated against the regular expression.

Note we expressly do not support the `eurodate` type, since date formats vary across EU countries. For this, prefer the `LSIsDate( date, locale )` method instead.
