#' module_energy_LA112.U
#'
#' Assigning global uranium supply curve to GCAM_region_ID 1.
#'
#' @param command API command to execute
#' @param ... other optional parameters, depending on command
#' @return Depends on \code{command}: either a vector of required inputs,
#' a vector of output names, or (if \code{command} is "MAKE") all
#' the generated outputs: \code{L112.RsrcCurves_Mt_R_U}. The corresponding file in the
#' original data system was \code{LA112.U.R} (energy level1).
#' @details Describe in detail what this chunk does.
