Class coordinates-axes defines 3D coordinates-axes drawable on a screen.
Each axis and an arrow at the tip of z-axis are defined by line objects.
Since the coordinates-axes class inherits cascaded-coords,
a coordinates-axes object can be attached
to another cascaded-coords originated object such as a body.
This object is used to see the coordinates-axes of a body or a
relative coordinates to another coordinates.
