/**

 * Responsive is a plug-in for the DataTables library that makes use of

 * DataTables' ability to change the visibility of columns, changing the

 * visibility of columns so the displayed columns fit into the table container.

 * The end result is that complex tables will be dynamically adjusted to fit

 * into the viewport, be it on a desktop, tablet or mobile browser.

 *

 * Responsive for DataTables has two modes of operation, which can used

 * individually or combined:

 *

 * * Class name based control - columns assigned class names that match the

 *   breakpoint logic can be shown / hidden as required for each breakpoint.

 * * Automatic control - columns are automatically hidden when there is no

 *   room left to display them. Columns removed from the right.

 *

 * In additional to column visibility control, Responsive also has built into

 * options to use DataTables' child row display to show / hide the information

 * from the table that has been hidden. There are also two modes of operation

 * for this child row display:

 *

 * * Inline - when the control element that the user can use to show / hide

 *   child rows is displayed inside the first column of the table.

 * * Column - where a whole column is dedicated to be the show / hide control.

 *

 * Initialisation of Responsive is performed by:

 *

 * * Adding the class `responsive` or `dt-responsive` to the table. In this case

 *   Responsive will automatically be initialised with the default configuration

 *   options when the DataTable is created.

 * * Using the `responsive` option in the DataTables configuration options. This

 *   can also be used to specify the configuration options, or simply set to

 *   `true` to use the defaults.

 *

 *  @class

 *  @param {object} settings DataTables settings object for the host table

 *  @param {object} [opts] Configuration options

 *  @requires DataTables 1.10.1+
