createCtrlList: Create a List to Control the Flow through Experiment
In ndphillips/ShinyPsych: An easy way to program psychology experiments using Shiny

Create a list of reactive values (see reactiveValues or https://shiny.rstudio.com/reference/shiny/latest/reactiveValues.html) with important variables needed to go through an experiment. Additional variables can be specified.

createCtrlList(
  firstPage,
  globIds,
  complCode = FALSE,
  complName = NULL,
  oVars = NULL,
  oVarVals = NULL,
  task = NULL
)

`firstPage`	string. The id of the first page to be displayed
`globIds`	string. A vector containing the ids of the different pages to be displayed (such as instructions or questionnaires but not tasks). Only pages that have a list either created by `createPageList` or are in the same form have to be indicated here. A hardcoded single page has not to be indicated here.
`complCode`	logical. If TRUE (default is FALSE) a completion code will be created and complName should be specified.
`complName`	string. Will be the beginning of the completion code. The completion code will be in the form "complName-XXX-XXX-XXX" where XXX is a randomly drawn number between 100 and 999. This code can then be displayed to the participant that he can enter e.g. as code on Amazon MTurk.
`oVars`	string. Vector with the name(s) of additional variables that should be added to ctrlList.
`oVarVals`	sting or numeric. Vector containing the values that should be appended to the oVars variables. Must be the same length as oVars.
`task`	string. Vector with names indicating which task will be played in the app. Valid inputs are: "bandit", "bart" "dfe", "dfd" or "dd" or any combination of these. For each given task the respective variables necessary will be appended.
