* Singleton.

* of objects are required in one call, e.g. to save memory in a
* CMS invironment where several parsers are required in a single page.
*
* $single = & singleton();
*
* or
*
* $single = & singleton('Parser', array('Prefilter', 'Delimiter', 'Code', 'Function',
* 'Html', 'Raw', 'Include', 'Embed', 'Anchor', 'Heading', 'Toc', 'Horiz',
* 'Break', 'Blockquote', 'List', 'Deflist', 'Table', 'Image', 'Phplookup',

* 'Colortext', 'Strong', 'Bold', 'Emphasis', 'Italic', 'Underline', 'Tt',
* 'Superscript', 'Subscript', 'Revise', 'Tighten'));
*
* Call using a subset of this list. The order of passing rulesets in the
* $rules array is important!
*
* After calling this, call $single->setParseConf(), setRenderConf() or setFormatConf()
* as usual for a constructed object of this class.
*
* The internal static array of singleton objects has no index on the parser
* rules, the only index is on the parser name. So if you call this multiple
* times with different rules but the same parser name, you will get the same
* static parser object each time.

* @since Method available since Release 1.1.0
* @param string $parser The parser to be used (defaults to 'Default').
* @param array $rules The set of rules to instantiate the object. This
* will only be used when the first call to singleton is made, if included
* in further calls it will be effectively ignored.
* @return &object a reference to the Text_Wiki unique instantiation.
