public class BitlineBuffer
extends GenericGate
implements Simulatable

BitlineBuffer: a non-inverting buffer that transfers Z into Z. We need this buffer for the RAM storage cell demo, because we cannot model the bitline-drives-against-weak-feedback buffer otherwise. transfer function:

     input_1164:   U X 0 1 Z W L H D
     output_1164:  U X 0 1 Z X 0 1 X
