start-app: Start 'RAVE' Applications
In dipterix/rave2:

Use start_rave to launch applications; use view_layout to debug module.

start_rave(
  host = "127.0.0.1",
  port = NULL,
  launch_browser = TRUE,
  test_mode = FALSE,
  token = NULL,
  theme = "green",
  .adapter = dipsaus::fastmap2()
)

`host`	IP address, default is `'127.0.0.1'`
`port`	integer port to listen to, default is `NULL`, and will be assigned a random port
`launch_browser`	whether to launch browser once the application is opened
`test_mode`	whether to enter test mode. Test mode does not release memory once application is closed, this will allow step-by-step debugging
`token`	token needed to launch application, default does not require any token
`theme`	passed to `dashboardPage`
`.adapter`	debug use, must be a `fastmap2` instance. Combined with `test_mode=TRUE`, `.adapter` stores all container/module instances.
