#' Import clusters description
#'
#' @description 
#' This function reads in the input files of an antares study the
#' characteristics of each cluster. 
#' 
#' Be aware that clusters descriptions are read
#' in the input files so they may have changed since a simulation has been run.
#'
#' @inheritParams readAntares
#'
#' @return
#' A data.table with one line per cluster. The columns of the data.table may
#' change between different projects, but there will always be the following 
#' columns:
#' 
#' \item{area}{Name of the area containing the cluster}
#' \item{cluster}{Name of the cluster}
#' \item{group}{Type of cluster (gaz, nuclear, etc.)}
#' \item{unitcount}{number of production units}
#' \item{nominalcapacity}{production capacity of each unit}
#' 
#' The other present columns depends on the version of antares and the options
#' that have been set: if an option is unset for all clusters, it will not 
#' appear in the table.
#' 
#' By default, the function reads the cluster description of the default antares
#' study. You can use the argument \code{opts} to specify another study.
#' 
#' \code{readClusterDesc} : read thermal clusters
#' 
#' \code{readClusterResDesc} : read renewable clusters (Antares >= V8.1)
