#' Gamma Log Likelihood Function
#'
#' The log likelihood of a gamma density with data, x, shape, rate
#' and scale parameters.
#'
#' @details The log likelihood is the log of a function of parameters given the data.
#'
#' @return A numeric scalar for the log likelihood of the gamma density given the
#' data where shape, scale, and rate can be held constant or if vector were given
#' vector will be returned.
