In this Crypto Zombie chapter we look at how we will be calculating our new zombie's dna. Once our zombie feeds on a human out feedAndMultiply function should create a new zombie from my zombies dna and the target human's dna that was fed on. This lesson helps us see how we will create a new zombie by taking zombieDna and our targetDna and then adding those 2 together, then dividing by 2 to get the average. The Result will be our new zombies dna. We finish it off by calling our _createZombie function and throw in a name for its first parameter( "NoName") and the new zombie's dna (newDna) as the second parameter.
