Record of known problems in SACAMOS

21/10/2019: A problem has been reported when using overshields. If the overshield is 
            not the last cable to be defined then the numbering of reference conductors
            (shields) in the bundle can be incorrect. Fixed 22/10/2019 CJS.
	    
23/10/2023: An error occurs if we try to include a transfer impedance which is purely resistive.
            The resistive part of the transfer impedance is lumped at the ends if the shield conductor
	    in the SACAMOS model and is always included so a resistive transfer impedance does not need
	    to be explicitly included as it is always there, however the error should be trapped and a 
	    warning shown.
