#' Get a url, with sensible defaults
#'
#' @export
#' @param .data A request object
#' @param ... Curl options passed on to \code{\link[httr]{GET}}.
#' @param parse (logical) Attempt to parse data to data.frame if possible. Default: TRUE
#' @details Attempts to simplify the http request process by using sensible defaults:
#' \itemize{
#'  \item GET by default: you most likely want to use \code{\link[httr]{GET}}
#'  \item You most likely want a data.frame back, so we attempt to coerce to a data.frame
