	= line 7 =		}
	= line 8 =		return $sum/$self->{_inputs_size};
	= line 9 =	}

Line 2 and 3 pulls in our sum and self refrence. Line 5 opens a loop to go over
all the input lines into this node. Line 6 looks at each input line's value 
and comparse it to the threshold. If the value of that line is below threshold, then
we return 0.000001 to signify a 0 value. (We don't return a 0 value so that the network
doen't get hung trying to multiply a 0 by a huge weight during training [it just will
keep getting a 0 as the product, and it will never learn]). Line 8 returns the mean 
value of all the inputs if all inputs were above threshold. 

Very simple, eh? :)
