AutoVisual/IGPTheGreatMosqueOfCordoba.pde: Adding setVectorsOnOuterSquare() function. Getting all PVectors for calculations from previously created lists, to save calculation time. Moving all stroke drawing to displayConstructionLines(). Also setting the PVector indicators on the outer square for better visibility. Aligning stroke and fill color with IGPTheGreatMosqueOfKairouan.
