Rules:
  * join your forces to increase the number on one position
  * bigger number wins, but takes up to smaller number damage
  * create new numbers:
    the patterns
        n   n
          n
    and
          n
        n   n
     spawns a number in the empty space, randint(1,3), but there
     is 1 in 10 chance it is a zombie and it will be from 
     the oposite team, beware!
  * things are sorted left to right, and top to bottom      
  * you can move +-2 in x and y direction

examples (red):

def evolve(red, blue, grid): 
    print(red)
    for r in red:
        r["x"] += 1
        r["y"] += 2
    return red

def evolve(red, blue, grid): 
    if grid[0][5] != None:
        grid[0][5]["y"] += 1
    return red

def evolve(red, blue, grid):
    for row in grid:
        for v in row:
            if v != None and "red" in v:
                v["x"] += 1
                v["y"] += 2
    return red

def evolve(red, blue, grid):
    for (i,r) in enumerate(red):
        if i % 2 != 0:
            r["y"] += 1
        else:
            r["y"] += 2
    return red

def evolve(red, blue, grid):
    for r in red:
        if r["x"] % 2 != 0:
            r["y"] += 1
        else:
            r["y"] += 2
    return red


def evolve(red, blue, grid):
    # you can print and use console.log to debug
    print(blue)
    return blue

or a javascript example:

function evolve({red,blue,grid}) {
    for (let r of red) {
        r.x ++
        r.y += 2
    }
    return red
}

* cheating
  there is some cheating allowed by modifying the grid state in 
  the location.hash, this is great opportunity to teach about 
  validating user input in practice.

  the format is [x,y,value,x,y,value...] so [2,1,-5] will 
  spawn 5 on x=2 and y=1
