However, I described a method used for an intersection of two directions
while this is a boundary loop...So here there would be one rotation value
and that same rotation value would be applied to all lines. And that's to
rotate the tract description directions (that are based on Federal land
subdivision) into a UTM directional orientation based on a UTM convergence
somewhere on the tract...
