Declares a class that represents a Probability Density Function (PDF) of a 3D pose (6D actually), by means of a 7-vector with a translation [x y z] and a quaternion [qr qx qy qz].
This class is just the base class for unifying many diferent ways this PDF can be implemented.
For convenience, a pose composition is also defined for any PDF derived class, changeCoordinatesReference, in the form of a method rather than an operator.
See also the tutorial on probabilistic spatial representations in the MRPT.
