relu6 is wrong

[allenxcp]

F.clip clip(x, a_min, a_max) = max(min(x, a_max), a_min))

relu6 = min(max(features, 0), 6)

[AmigoCDT]

relu6(x) let the activation of x in [0, 6], when x <= 0 or x>=6, activation is 0 or 6.
clip(x, a_min, a_max) does the same thing. min after max and max after min have same activations.
This implement is right.
