This class provides simple access to csv files and let you easy
navigate through the tabel.

You should only access one of the following functions and
variables:

Variables:

$index				// Index in File, DO NOT CHANGE
$limiter			// The CVS Limiter, usually ";"
$filename			// The filename of the cvs file
$record = array()	// The actual record
$EOF				// True if End of File
$BOF				// True if Beginning of File

Functions:

function open_db()
- opens file
- puts first recordset into record
- returns 1 if ok, 0 if not

function move_next()
- loads the next recordset

function move_pref()
- loads the previous recordset

function move_first()

function move_last()
- same as above, only last

function close()
- closes the filehandler

function update()
