This function tests a generic_spct object for an attribute that
signals whether the spectral data has been normalized or not after the object
was created.
is_normalized(x)is_normalised(x)
A logical value indicating if x is normalized or not,
for collections of spectra, a named list with logicals as members.
If x is not a generic_spct or generic_mspct object the
value returned is NA.
An R object.
