/**
* Get a `dt-tag td` node from a row, taking into account column visibility.
* While getting a `dt-tag td` node is easy when it is visible on the page by
* using normal DOM methods, jQuery or whatever, it becomes a lot more
* complicated when taking into account hidden rows and columns. This function
* can be used to overcome these difficulties.
*
* DataTables 1.10+'s new API provides the `dt-api cell()` and `dt-api cells()`
* methods which are preferable for use over this method. As such this method is
* marked deprecated, but is available for use with legacy version of
* DataTables. Please use the new API if you are used DataTables 1.10 or newer.
*
* @name fnGetTd
* @summary Get the `dt-tag td` element for a cell.
* @author [Allan Jardine](http://sprymedia.co.uk)
* @deprecated
*
* @param {node} mTr `dt-tag tr` element to get the `dt-tag td` of
* @param {integer} iTd Column index to get the node of
* @param {boolean} bVisOnly Consider visible columns only
* @returns {node} `dt-tag td` element in question
*
* @example
* $(document).ready(function() {
* var table = $('#example').dataTable();
*
* // Sort in the order that was origially in the HTML
* var nTd = table.fnGetTd( $('#example tbody tr:eq(1)')[0], 1 );
* console.log( nTd );
* } );
