/*	This file contains the files necessary to display news as an XML feed.

	void ShowXmlFeed()
		- is called to output xml information.
		- can be passed four subactions which decide what is output: 'recent'
		  for recent posts, 'news' for news topics, 'members' for recently
		  registered members, and 'profile' for a member's profile.
		- To display a member's profile, a user id has to be given. (;u=1)
		- uses the Stats language file.
		- outputs an rss feed instead of a proprietary one if the 'type' get
		  parameter is 'rss' or 'rss2'.
		- does not use any templates, sub templates, or template layers.
		- is accessed via ?action=.xml.

	void dumpTags(array data, int indentation, string tag = use_array,
			string format)
		- formats data retrieved in other functions into xml format.
		- additionally formats data based on the specific format passed.
		- the data parameter is the array to output as xml data.
		- indentation is the amount of indentation to use.
		- if a tag is specified, it will be used instead of the keys of data.
		- this function is recursively called to handle sub arrays of data.

	array getXmlMembers(string format)
		- is called to retrieve list of members from database.
		- the array will be generated to match the format.
		- returns array of data.

	array getXmlNews(string format)
		- is called to retrieve news topics from database.
		- the array will be generated to match the format.
		- returns array of topics.

	array getXmlRecent(string format)
		- is called to retrieve list of recent topics.
		- the array will be generated to match the format.
		- returns an array of recent posts.

	array getXmlProfile(string format)
		- is called to retrieve profile information for member into array.
		- the array will be generated to match the format.
		- returns an array of data.
