vcr: Record 'HTTP' Calls to Disk

#' @section Backstory:
#' A Ruby gem of the same name (`VCR`, <https://github.com/vcr/vcr>) was
#' created many years ago and is the original. Ports in many languages
#' have been done. Check out that GitHub repo for all the details on
#' how the canonical version works.
#'
#' @section Main functions:
#' The [use_cassette] function is most likely what you'll want to use. It
#' sets the cassette you want to record to, inserts the cassette, and then
#' ejects the cassette, recording the interactions to the cassette.
#'
#' Instead, you can use [insert_cassette], but then you have to make sure
#' to use [eject_cassette].
#'
#' @section vcr configuration:
#' [vcr_configure] is the function to use to set R session wide settings.
#' See it's manual file for help.
#'
#' @section Record modes:
#' See [recording] for help on record modes.
#'
#' @section Request matching:
#' See [request-matching] for help on the many request matching options.
