In a large bowl, dissolve the sugar and salt into the water. Add the oil and flour to the bowl and stir with a heavy spoon for one minute.
Turn the dough out onto a lightly floured surface and press into a circle. Sprinkle the yeast evenly over the dough and knead for twelve minutes.
Divide the dough into portions - four equal portions for calzones, three equal portions for 8" pizzas or two equal portions for 12" pizzas. Place the dough balls into a bowl, cover with plastic wrap and allow to rise for 1.5 hours in a warm location.
Place a dough ball on a lightly floured surface and sprinkle a light coating of flour on top. Working from the edges to the center, press the dough into a circle.
Preheat a pizza stone in a 500 degree oven for one hour. Coat a large cutting board with the cornmeal and place the flattened dough onto the cornmeal. Spread the sauce over the crust and top with cheese and your desired toppings.
Gently shake the cutting board from side to side assuring that it is not sticking to the board.
For a calzone, fold the crust over in half. Slide the pizza or calzone from the cutting board directly onto the stone in the oven.
Bake at 500 degrees for 20-25 minutes until the crust is golden et voila!
