  envir = NULL,
  clear_environment = FALSE,
  keep = NULL

clear_environment	When TRUE, will remove objects not named in ...
keep	a regular expression of objects to keep when clear_environment = TRUE

  system.file(package = "shinyobjects", "Rmd/test_dashboard.Rmd") %>%
    load_reactive_objects()

  system.file(package = "shinyobjects", "Rmd/test_dashboard_no_inputs.Rmd") %>%
