chapter 16 minHeap misspelled method

[ljmerza]

if (this.rightChild(index) && this.rightChild(index) < this.items[smallerIndex]) {
    // if right is smaller, right swaps
    smallerIndex = this.rightChildrenIndex(index);
}

rightChildrenIndex doesn't exist I think you meant rightChildIndex

EDIT: I realized this is a mistake on my part. rightChildrenIndex is defined and rightChildIndex is not. It was a little confusing when typing up the implementation because the left child is called leftChildIndex and leftChild and the right side node getter is rightChild so it made sense for the right side index getter to be rightChildIndex
