Documented in generateBiocPkgDOI

#' Generate a DOI for a Bioconductor package
#'
#' This function makes calls out to the DataCite REST API described
#' here: \url{https://support.datacite.org/docs/api-create-dois}. The
#' function creates a new DOI for a Bioconductor package (cannot already
#' exist). The target URL for the DOI is the short Bioconductor
#' package URL.
#'
#' The login information for the "real" Bioconductor account
#' should be stored in the environment variables "DATACITE_USERNAME"
#' and "DATACITE_PASSWORD
#'
#' The GUI is available here: \url{https://doi.datacite.org/}.
#'
#' @param pkg character(1) package name
#' @param authors character vector of authors (will be "pasted" together)
#' @param pubyear integer(1) publication year
#' @param event Either "hide", "register", or publish". Typically, we use
#'     "publish" to make the DOI findable.
#' @param testing logical(1) If true, will use the apitest
#'     user with the password apitest. These DOIs will expire.
#'     The same apitest:apitest combination can be used to
#'     login to the website for doing things using the
#'     web interface. If false, the Bioconductor-specific
#'     user credentials should be in the correct environment
#'     variables
#'
#' @return The DOI as a character(1) vector.
