+ * Function: fnGetColumnData
+ * Purpose:  Return an array of table values from a particular column.
+ * Returns:  array string: 1d data array 
+ * Inputs:   object:oSettings - dataTable settings object. This is always the last argument past to the function
+ *           int:iColumn - the id of the column to extract the data from
+ *           bool:bUnique - optional - if set to false duplicated values are not filtered out
+ *           bool:bFiltered - optional - if set to false all the table data is used (not only the filtered)
+ *           bool:bIgnoreEmpty - optional - if set to false empty values are not filtered from the result array
