/*                      If three:
          i = # of *   j = # of space
      |  *  | i = size-2   j = 2
      | *** | i = size-1   j = 1
      | *** |
      |*****| i = 0;       j = ((size*2)-1)
      |*****|
      |*****| height = 6
----------------------------------------------------------------------------------------------------------------
            If four:
     |   *   |  i = 1     j = 3
     |  ***  |  i = i+2   j = 2     --- row appears 2 times
     |  ***  |
     | ***** |  i = i+2   j = 1     --- row appears 3 times
     | ***** |
     | ***** |
     |*******|  i = i+2   j = 0     --- row appears 4 times (see the pattern?)
     |*******|
     |*******|
     |*******|  height = 10...so there is no 'height' variable, it's how many times it will enter a loop.
            For example, the 3 tree hits the loop...3 times. Here, it hits it 4 times, since there
            are 4 different numbered rows of stars. Each loop will increase i (or the star value) by +2.

            But what I need to figure out is how to calculate j...how to calculate the spaces...
            Here, it actually looks like the first loop would be (j = size-1)
            Then it continues to decrement, so j will go... for(j>=0) { --j}, as long as j is initalized as (size-1)
