Added SR flip-flop and T flip-flop

SR FF:
S = input[0]
R = input[1]
Clock = input[2]
Q = output[0]
!Q = output[1]
T FF:
T = input[0]
Clock = input[1]
Q = output[0]
!Q = output[1]
Added JK flip-flop

J = inputs[0]
K = inputs[1]
Clock = inputs[2]
Q = outputs[0]
!Q = outputs[1]
Added D flip-flop

D = inputs[0]
Clock = inputs[1]
Q = outputs[0]
!Q = outputs[1]
Added memory section with flip flops (DFF, TFF, JKFF, SRFF)
