#' Set Path to an Antares simulation
#'
#' This function has to be used before the \code{read} functions. It sets the path to
#' the Antares simulation to work on and other useful options (list of areas,
#' links, areas with clusters, variables, etc.). On local disk with \code{setSimulationPath} or
#' on an AntaREST API with \code{setSimulationPathAPI}
#'
#' @details
#' The simulation chosen with \code{setSimulationPath} or \code{setSimulationPathAPI} becomes the default
#' simulation for all functions of the package. This behavior is fine when
#' working on only one simulation, but it may become problematic when working
#' on multiple simulations at same time.
#'
#' In such case, you can store the object returned by the function in a variable
#' and pass this variable to the functions of the package (see examples).
#'
#' @param path (optional)
#' Path to the simulation. It can either be the path to a directory containing
#' an antares project or directly to the directory containing the output of a
#' simulation. If missing, a window opens and lets the user choose the
#' directory of the simulation interactively. Can also choose .h5 file, if \code{rhdf5} is installed.
#' @param simulation
#' (optional) Only used if "path" represents the path of a study and not of the
#' output of a simulation. It can be either the name of the simulation or a
#' number indicating which simulation to use. It is possible to use negative
#' values to select a simulation from the last one: for instance -1 will
#' select the most recent simulation, -2 will the penultimate one, etc. There
#' are two special values 0 and "input" that tells the function that the user
#' is not interested by the results of any simulation, but only by the inputs.
#' In such a case, the function \code{\link{readAntares}} is unavailable.
#'
#' @param host \code{character} host of AntaREST server API
#' @param study_id \code{character} id of the target study on the API
#' @param token \code{character} API personnal access token
#' @param timeout \code{numeric} API timeout (seconds). Default to 60. See also \code{\link{setTimeoutAPI}}
#' @param httr_config API httr configuration. See \code{\link[httr]{config}}
#'

#' }

#' \item{start}{
#' Date of the first day of the year in the simulation. This date corresponds
