Convert wikipedia style markup to HTML using MediaWiki class

Write a single function that accesses MediaWiki (1.18.1 = latest version) parser functionality to convert Wikipedia wikitext notation to HTML. Buyer will have a html directory on a server, with a subdirectory 'mediawiki', into which he will place all the files from mediawiki-1.18.1 (as downloaded from [login to view URL]). You will put a file into the base html directory that access these downloaded open source classes. Coder needs to write [login to view URL] which contains function Convert($sInputWikiText); $sInputWikiText = a string of wikitext e.g. '''embolden the text''' return value should be HTML e.g. <b>embolden the text</b> Buyer will test the functionality by running typical tutorial wikitext notation examples e.g. [login to view URL]:Table to test that 'Convert' function works as expected, producing the equivalent HTML
