Defines functions block_title

Documented in block_title

#' A block with large title text
#'
#' With `block_title()` we can define a title text area and this can be easily
#' combined with other `block_*()` functions. The title will take the entire
#' width of the block and will resize according to screen width. Like all
#' `block_*()` functions, `block_title()` must be placed inside of `blocks()`
#' and the resultant `blocks` object can be provided to the `body`, `header`, or
#' `footer` arguments of `compose_email()`.
#'
#' @param title Plain text or Markdown text (via [md()]) for the title.
#'
#' @examples
#' # Create a block of two, side-by-side
#' # articles with two `article()` calls
#' # inside of `block_articles()`, itself
#' # placed in `blocks()`; also, include a
#' # title at the top with `block_title()`
