     This function returns an multidimensional array containing a list of
     all defined functions, both built-in (internal) and user-defined. The 
     internal functions will be accessible via
     <varname>$arr["internal"]</varname>, and the user defined ones using
     <varname>$arr["user"]</varname> (see example below).
