/**
* Links (ie: URLs) can be associated with fields of a table by defining a "link"
* property for a field in the fields.ini file or by defining a fieldname__link()
* method in the delegate class. These links are accessible via the Table::getLink()
* method which resolves any variables in the link provided and returns the link
* in the same format as it is defined in its place of origin (either the fields.ini file
* or the delegate class.
*
* Links can be in the form of a query array, or in the form of a string (which should
* be a url).
* In this test, `fname`, `lname`, and `description` fields have links defined in the
* Profiles delegate class.
