;18 point cell with variable angles -- two rings: 6*(1+2)

;Basically the standard GuiPlop 18-point varying angle cell, however 

;it is ready to be used as a variable force cell by simply changing 

;(or optimizing) the value of f1.

;Can support a 21x1in plate glass f/6 mirror w/ no refocus and 10% obs.

;or a 31x2in pyrex f/5 mirror w/ no refocus and 10% obs.
