Starting with the most cumbersome function:

function read($start,$offset,$fields,$query="",$filter="",$sort="",$order="")

	Purpose:
		Returns a list of contacts based on limits, query, and filter,
		in an array of name/values, e.g.:

			$fields[0]["id"]    => "354",
			$fields[0]["email"] => "name@domain.com", ...

			$fields[1]["id"]    => "355",
			$fields[1]["email"] => "othername@otherdomain.com", ...

	Inputs:

		$start = start of list, e.g. 1,16,31
		$offset = numrows, e.g. 15,30,etc. from nextmatchs, usually
		$fields = simple array of fields to return:

			$qfields = array(
				'id' => 'id',
				'n_given' => 'n_given
			);

		$query = simple string to search for, e.g. "milosch" or "555"

		$filter = for 'accounting' fields other than id (use read_single_entry for
		that):

			owner  = account_id of record owner
			access = public/private
			cat_id = category id for the record
			lid    = account_lid for account records stored here, if any
			tid    = type id:
				n = normal contact - almost always use this
				p = profiles for hr, tied to account records
				u = user account, if stored in contacts class
				g = group account, ""
		
			Filters should be in the format:

				example 1: 'tid=n'				filter for normal contacts
				example 2: 'tid=u,lid=milosch'	filter user accounts for lid
												'milosch'
				etc...

		$sort = ASC, DESC, or "" (defaults to ASC)

		$order = sort on this field, e.g. n_given


function read_single_entry($id,$fields)

	Purpose:
		returns a single array of name/value based on id
		and field selection, e.g.:

			$fields[0]["email"]   => "name@domain.com"
			$fields[0]["n_given"] => "Bob"

	Inputs:

		$id = id of entry you want to return
	
		$fields = simple array of fields to return

			$qfields = array(
				'id' => 'id',
				'n_given' => 'n_given
			);


function add($owner,$fields,$access='',$cat_id='',$tid='n')

	Purpose:

		Add a new contact record of the type, category and access sent
		with a field list.

	Inputs:

		$owner  =	id of user adding this data

		$fields =	simple array of fields to write into the new record

		$access =	public/private

		$cat_id =	category id for the record, if desired

		$tid    =	type id ( see read() above ), defaults to 'n'


function update($id,$owner,$fields,$access='',$cat_id='',$tid='')

	Purpose:

		Update an entry already in the contacts list

	Inputs:

		$id     =	id of entry you want to update
		
		$owner  =	id of user modifying this data
		
		$fields =	simple array of fields to update in the record
					(see examples above)

		$access =	public/private

		$cat_id =	category id for the record, if desired


		$tid    =	type id ( see read() above ), defaults to 'n'


function delete_($id)

	Purpose:

		Delete an entry already in the contacts list

	Inputs:

		$id = id of entry you want to delete
