/**
* Main IPSclass class.
*
* This is the main class which is referenced via $ipsclass throughout
* all the IPB sub-classes and modules. It holds amongst others:
* <code>
* // Object from class_forums.php class
* $ipsclass->forums
* // Object from class_display.php class
* $ipsclass->print
* // Object from SQL classes
* $ipsclass->db
* // Array of parsed caches  (from table cache_store)
* $ipsclass->cache
* // Array of settings variables (taken from parsed setting cache)
* $ipsclass->vars
* // Array of member variables (taken from class_session::$member)
* $ipsclass->member
* // Array of sanitized _GET _POST data (run via parse_clean_value)
* $ipsclass->input
* // Array of language strings loaded via separate lang files
* $ipsclass->lang
* // Variable: Full base URL with session ID if required
* $ipsclass->base_url
* // Array of compiled template objects
* $ipsclass->compiled_templates
* </code>
* Recommended method of passing $ipsclass through modules
* <code>
* $module           = new module();
* $module->ipsclass =& $ipsclass; // Create reference
* </code>
