#' @param command API command to execute
#' @param ... other optional parameters, depending on command
#' @return Depends on \code{command}: either a vector of required inputs,

#' the generated outputs: \code{L112.RsrcCurves_Mt_R_U}. The corresponding file in the
#' original data system was \code{LA112.U.R} (energy level1).
