/**
* 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 jQuery 1.7+
* @requires DataTables 1.10.3+
*
* @example
* $('#example').DataTable( {
* responsive: true
* } );
* } );
