Superellipse.
A profile based on superellipses is composed of an upper and a lower semi-ellipse, which may differ from each other in their parameterization. The total width and height of the profile is always 1, since scaling is performed after referencing (e.g., in the fuselage). This lowerHeightFraction describes the portion of the lower semi-ellipse on the total height. The resulting profile is defined by the following set of equations:

superEllipseExample1 Example 2 : ( mUpper,nUpper,mLower,nLower, lowerHeightFraction ) = (2; 2; 2; 2; 0.5) = a circle

superEllipseExample2 Example 3 : ( mUpper,nUpper,mLower,nLower, lowerHeightFraction ) = (1; 1; 1; 1; 0.5) = a square / diamond

superEllipseExample3 Note : For exponents that are infinitely large, the superellipse converges to a rectangle. However, the value Inf is not a valid entry at this point. Use the square element instead.
