This class handles hyperspectral data sets, i.e. spatially or time-resolved spectra, or spectra with any other
kind of information associated with the spectra.The spectra can be data as obtained in XRF, UV/VIS, Fluorescence, AES,
NIR, IR, Raman, NMR, MS, etc.
More generally, any data that is recorded over a discretized variable, e.g. absorbance = f (wavelength), stored as a vector of absorbance values for discrete wavelengths is suitable.
