 **isISRC(str)**                         | check if the string is a [ISRC](https://en.wikipedia.org/wiki/International_Standard_Recording_Code).
 **isIn(str, values)**                   | check if the string is in a array of allowed values.
 **isInt(str [, options])**              | check if the string is an integer.<br/><br/>`options` is an object which can contain the keys `min` and/or `max` to check the integer is within boundaries (e.g. `{ min: 10, max: 99 }`). `options` can also contain the key `allow_leading_zeroes`, which when set to false will disallow integer values with leading zeroes (e.g. `{ allow_leading_zeroes: false }`). Finally, `options` can contain the keys `gt` and/or `lt` which will enforce integers being greater than or less than, respectively, the value provided (e.g. `{gt: 1, lt: 4}` for a number between 1 and 4).
