/**
 * Sorts a column containing IP addresses in typical dot notation. This can 
 * be most useful when using DataTables for a networking application, and 
 * reporting information containing IP address. Also has a matching type 
 * detection plug-in for automatic type detection.
 *
 *  @name IP addresses 
 *  @summary Sort IP addresses numerically
