**  checkLength($field, $min, $max, $msg='', $allowNull) - //
**  checkIdentical($field, $field2, $msg='', $allowNull) - // used for testing against dual passwords or email entry
  checkIsValidEmail($field, $msg='', $allowNull) - // email validation only regex not MX records
  checkIsText($field, $msg='', $allowNull) - // not needed as alphanumrec is the same sort of thing
  checkIsAlphabetic($field, $msg='', $allowNull) - // same as checkIsNumeric but text only no special characters
  checkIsDigit($field, $msg='', $allowNull) - // same as checkIsNumeric but 0-9 only
  checkIsAlphanum($field, $msg='', $allowNull) - // essentially no special characters
**  checkPassword($field, $field2, $min, $max, $msg='', $allowNull)
