Description: Definitions of classes, methods, operators and functions for use 
    in photobiology and radiation meteorology and climatology. Calculation of
    effective (weighted) and not-weighted irradiances/doses, fluence rates,
    transmittance, reflectance, absorptance, absorbance and diverse ratios and 
    other derived quantities from spectral data. Local maxima and minima: peaks,
    valleys and spikes. Conversion between energy-and photon-based units. 
    Wavelength interpolation. Colours and vision. This package is part of the 
    'r4photobiology' suite, Aphalo, P. J. (2015) <doi:10.19232/uv4pb.2015.1.14>.
