#' Delete Project, Scenario, Folder, Chart or Datasheet
#'
#' @details
#' Deletes one or more items. Note that this is irreversible. To delete
#' a library, you must use the \code{\link{deleteLibrary}} function instead.
#'
#' @param ssimObject \code{\link{SsimLibrary}}, \code{\link{Project}},
#'     \code{\link{Scenario}}, \code{\link{Folder}}, or \code{\link{Chart}} 
#'     object
#' @param project character string, numeric, or vector of these. One or more 
#'     \code{\link{Project}} names or ids. Note that project argument is ignored 
#'     if ssimObject is a list. Note that integer ids are slightly faster (optional)
#' @param scenario character string, numeric, or vector of these. One or more 
#'     \code{\link{Scenario}} names or ids. Note that scenario argument is 
#'     ignored if ssimObject is a list. Note that integer ids are slightly faster 
#'     (optional)
#' @param folder character string, numeric, or vector of these. One or more 
#'     \code{\link{Folder}} names or ids. Note that folder argument is 
#'     ignored if ssimObject is a list. Note that integer ids are slightly faster 
#'     (optional)
#' @param chart character string, numeric, or vector of these. One or more 
#'     \code{\link{Chart}} names or ids. Note that chart argument is 
#'     ignored if SsimObject is a list. Note that integer ids are slightly faster 
#'     (optional)
#' @param datasheet character string or vector of these. One or more datasheet 
#' names (optional)
#' @param force logical. If \code{FALSE} (default), user will be prompted to approve 
#'     removal of each item
#' @param session \code{\link{Session}} object. If \code{NULL} (default), session()
#'     will be used. Only applicable when `ssimObject` argument is a character
#' 
#' @return 
#' Invisibly returns a list of boolean values corresponding to each
#' input: \code{TRUE} upon success (i.e.successful deletion) and \code{FALSE} upon failure.

# Note delete no long supports character paths as the ssimObject.
# Note delete supports project/scenario/folder/chart arguments because sometimes
