/**
* This sorting type will replace DataTables' default string sort with one that
* will use a locale aware collator. This is supported by IE11, Edge, Chrome,
* Firefox and Safari 10+. Any browser that does not support the Intl will
* simply fall back to UTF8 string sorting.
*
* This method simply needs to be called prior to the DataTables' initialisation
* to replace the default string sort with locale aware sorting. The method
* optionally takes two arguments:
*
* 1. [Optional] Locale or array of locales
* 2. [Optional] Collator options
*
* For the supported options please see the
* [MDN Intl documentation](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Collator).
