EMSC: Extended Multiplicative Signal Correction

#' @name fishoil
#' @title Raman spectra of fish oil
#'
#' @description 42 fish oil samples with 3 replicates each constitute a Raman data set of 126
#' samples over 3471 Raman shifts. There is a large fluorescence signal in the spectra that
#' needs to be removed before any data analysis can be performed.
