* ------------------
* First, you have an outer loop that says, "Start the next row". It does this by,
* once you've made a row, removing one of the bricks from Bricks_In_Base so that
* the second row is one brick shorter, and by moving the starting brick up by
* 1 brick-height up and 1/2 brick-width to the right.
*
* Second, you have an inner loop that says "Make a row." It does this by
* placing down a brick in the starting location, then adding Brick_Width to
* the x coordinate and laying another brick at the new x-coordinate, repeated
* until you get to the end of the number of bricks in your row
* (or, until the index j gets to Bricks_In_Base.)
