#' Negative Binomial Log Likelihood Function
#'
#' The log likelihood of a negative binomial density with data, x, size, prob
#' and mu 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 negative binomial
#' density given the data where size, prob, and mu can be held constant or if
#' vector were given vector will be returned.
