A utility function which looks for gr.crit in the file names of .csv
files and assigns group membership (max 8 groups automatically). Also assigns a color, a symbol and an
alternate symbol to each group. Warnings are given if there are file names
that don't match entries in gr.crit or there are entries in
gr.crit that don't match any file names. An internal function, not
generally called by the user.
groupNcolor(spectra, gr.crit = NULL, gr.cols = c("auto"))An object of S3 class Spectra. Until this
function acts on spectra it is not quite complete.
As per files2SpectraObject.

Spectra will not pass checks as the assembly is not complete
(see chkSpectra).
