A class for doing comparisons between conceptual spectra, since the spectra do not possess a
self-ordering relation, they should be ordered with respect to a given reference spectra.
A java class for representing conceptual spectra, such class encapsulates all information
required in the definition of a conceptual spectra providing methods for evaluating the distance
between spectra according to a similarity value defined as:
a*formSimilarity+(1-a)*energySimilarity
