/** This calss performs the interpolation of two Spectrum processing data
* objects.
* <p>
* It Allows any possible attribute configuration in its inputs and in
* its output, but it performs faster when prototype configuration of
* the data is specified using SetPrototypes(...), in certain
* situations:
* <ul>
* <li> When all the inputs and the outputs have a common attirbute
* (not the BPF), and the same scale.
* <li> When one of the inputs has just a BPF attribute, and both the
* other input and the output have a common (non-BPF) attribute
* with the same scale in both objects.
* <li> In other cases, at least a vector conversion will be executed
* in one of the involved processing data objects. In some bad
* situations two conversions might be needed.
* </ul><p>
* @todo
* Possible optimisations (which require more states):
* <ul>
* <li> Implement direct sum routines with inputs/outpust in
* different formats, and Interpolate the corresponding prototype states.
* <li> Expand the state space to avoid checking if the attribute to be
* used in the computation is instantiated in each of the objects.
* Right now the same state is used when the three objects have a
* common attribute, and when a common attribute is to be used, but
* some of the objects lack it (and need format conversion).
* </ul>
* <p>
* The BPFxBPF sum is being thought. If both BPFs have the same
* range and point possition, the way to go is obvious, but in other
* situations it is not so simple. Whe should probably merge both
* BPFs, into a new BPF. */
