// Accepts a lotObject and returns its position as if the lot were plopped at 
// tile (0,0) - i.e. the NW corner of a city with the given orientation as the 
// orientation of the **lot** in the city. Note that this is a bit special 
// because in the Lot Editor, a lot is shown as having an orientation that would 
// correspond to orientation 2 in the city - i.e. facing *South*. City 
// orientation 0 is actually facing *North*, so we have to account for that.
