Defines functions gtm_auth

Documented in gtm_auth

#' Authenticate this session
#'
#' A wrapper for \link[googleAuthR]{gar_auth} and \link[googleAuthR]{gar_auth_service}
#'
#' @param new_user If TRUE, reauthenticate via Google login screen
#' @param no_auto Will ignore auto-authentication settings if TRUE
#'
#' If you have set the environment variable \code{GCE_AUTH_FILE} to a valid file location,
#'   the function will look there for authentication details.
#' Otherwise it will look in the working directory for the `.httr-oauth` file, which if not present
#'   will trigger an authentication flow via Google login screen in your browser.
#'
#' If \code{GCE_AUTH_FILE} is specified, then \code{gce_auth()} will be called upon loading the package
#'   via \code{library(googleComputeEngineR)},
#'   meaning that calling this function yourself at the start of the session won't be necessary.
#'
#' \code{GCE_AUTH_FILE} can be either a token generated by \link[googleAuthR]{gar_auth} or
#'   service account JSON ending with file extension \code{.json}
#'
#' @return Invisibly, the token that has been saved to the session
#' @import googleAuthR
#' @export
