Given any string this function returns true iff the string is accepted by all registered Validators (added by StackedValidator:addValidator).

If no Validator is registered this function always returns true. If one or more Validators reject the string, the fail text of the failing Validator that was added the earliest will be chosen.

Parameters
input- The input string
Returns
true iff the string is considered valid (accepted by all validators)
