/**
* Telephone numbers are a common data point to display in HTML tables, and are
* often formatted (e.g. `dt-string 555-1234`). Typically, when searching a
* table a user would need to enter the number in exactly the same format it is
* displayed in, but this is not always convenient (e.g. you might search for
* `dt-string 5551`).
*
* This filtering plug-in will allow both forms to be matched be providing both
* the formatted and de-formatted data to the table's search.
*
* @summary Make phone numbers searchable formatted or unformatted
* @name Phone number

'' :
