Create a new web play object

new_wp(game, bots, human = draw_human_pos(human_draw_method =
  human_draw_method, numPlayers = game$vg$params$numPlayers, human = 0),
  human_draw_method = c("cycle", "random", "fixed")[1], wpUI = "wpUI",
  verbose = FALSE, pages.dir = file.path(getwd(), "pages"),
  custom = list(), pre.page.handler = NULL, post.page.handler = NULL,
  finish.handler = wp.default.finish.handler,
  comp.pages = as.environment(list()), page.ui.fun = NULL, ...)

`game`	A gtree game generated with `new_game`.
`bots`	A list with one bots for every player. Also add a bot for the human player. You can call `make_bots` to conveniently create the bots.
`human`	index of the player that is played by a human in the first play of the web app.
`human_draw_method`	Method how the index of the human player is determined by default if a new play is started. The default `"cycle"` lets the human cycle through all players. `"random"` picks a random player, and `"fixed"` keeps the current player.
`wpUI`	the id of the `uiOutput` element in the app ui where the web play will be shown.
`verbose`	shall information about state of play be printed to the standard output?
`pages.dir`	the directory in which the Rmd files for the stage pages can be found. By default `"./pages"`.
`custom`	A list of custom parameters that will be passed to handlers.
`pre.page.handler`	a function that is called before a page is shown to a human. It should return a list of values that can be accessed in the whiskers of the page Rmd file.
`post.page.handler`	a function that is called after a human made input in a stage. Can for example be used to update a population play summary. (See the KuhnPoker example)
`finish.handler`	is called when the final results page of a play is left. The default handler simply starts a new play.
`page.ui.fun`	optionally a function that returns for each page a shiny tag that will be shown. If NULL (default) we specify the page ui via Rmd files in the pages subfolder.
