this is a quaternion class
...
it is meant to represent any quaternion, not only unit
quaternions/rotations that follow a specific convention. Need to check
in rotations.f90 where the homomorph should happen

consistent type handling and stronger encapsulation
...
components of quaternion are private now
qu is an array, not a quaterion (as in the python module). conceptually
cleaner because eu,ax,om, etc. are also plain array

don't clutter the code with useless stuff
...
we only need to be more strict about prefixing
functions/subroutines/variables to see in which module they reside

avoiding numerical errors (if quaternion norm is > 1.)
...
use consistently "self" instead of "this"
