#' @title Methods and accesors for \code{GenomicSignatures} object
#'
#' @description The default contents of \code{GenomicSignatures} object, with
#' a set of getter and setter generic functions, which extract either the
#' \code{assay}, \code{colData}, or \code{metadata} slots of a
#' \code{\link{GenomicSignatures-class}} object. When you create this object,
#' \code{colData$studies} should be populated before adding any information in
#' \code{trainingData} slot.
#'
#' @details
#' \itemize{
#'     \item assay(x) : RAVindex (= avgLoadings) containing genes x RAVs
#'     \item metadata(x) : Metadata associated with RAVindex building process
#'     \item colData(x) : Information on RAVs
#' }
#'
#' @section Setters:
#' Setter method values (i.e., \code{function(x) <- value}):
#' \itemize{
#'     \item metadata<- : Assign metadata
#'     \item coldata<- : Assign extra information associated with RAVs
#'     \item geneSets<- : A character vector containing the name of gene sets
#'     used to annotate average loadings
#'     \item updateNote<- : A character vector. Describes the main feature of a
#'     model construction
#' }
#'
#' @section Getters:
#' \itemize{
#'    \item RAVindex : Equivalent to \code{assays(x)$RAVindex}
#'    \item geneSets : Access the \code{metadata(x)$geneSets} slot
#'    \item updateNote : Access the \code{metadata(x)$updateNote} slot
#'    \item version : Access the \code{metadata(x)$version} slot
#' }
#'
#' @param x A \code{GenomicSignatures} object
#' @param value See details.
#'
#' @return A GenomicSignatures object for the constructor
