Symmetry Properties of Molecules
    In this exercise, symmetry operations can be examined
for a particular molecule.
    Sometimes a reorientation of the molecule is needed for a better view of the operation (or due to the way that Chime performs rotations for example). In that cases the following sequence will be shown:
reorientation-delay- symmetry operation -delay-back to original orientation
An example: a C2 for BF3: (push the square button)
