How it works
Reads from two 8-bit input and creates a weighted sum
of the 16 bits.
The 8-bit wieights are default 10000000 and are unuptatable. (10000000 represents 0.5 if the you conceptualize a . on the far left or represents 128 if you conceptualize a . on the far right)
If the weighted sum is greater than the threshold, 11111110, than it will classify the input as 1 otherwise it will classify it as 0.
9 + 10 = 21

How to test
Any input with all 0's should be classified as 0.
Math:
Note: The threshold is 11111110 which can be thought of as 0.99993896484
w0i0 + w1i1 + ... + w15*i15
0.50 + 0.50 + ... + 0.5*0 = 0
Any input with fifteen 0's and one 1's should be classified as 0.
Math:
w0i0 + w1i1 + ... + w15*i15
0.51 + 0.50 + ... + 0.5*0 = 0.5
Any input with two or more 1's should be classified as 1.
Math:
w0i0 + w1i1 + w2i2 + ... + w15i15
0.51 + 0.51 + 0.50 + ... + 0.50 = 1
0.51 + 0.51 + 0.51 + 0.50 + ... + 0.5*0 > 1
