Row by Row collision box layer based upon window inner height/size.

windowCollisionBox.js

function windowCollisionBox() {
  var width = window.innerWidth;
  var height = window.innerHeight;
  var grid = [];
  rowNum = 0;
  while(rowNum <= height) {
    if(!rowNum || rowNum == height){ // First and Last Row
      colNum = 0;
