Run UCSC Xena Shiny App

Usage

app_run(runMode = "client", port = getOption("shiny.port"))

runMode: default is 'client' for personal user, set it to 'server' for running on server.
port: The TCP port that the application should listen on. If the port is not specified, and the shiny.port option is set (with options(shiny.port = XX)), then that port will be used. Otherwise, use a random port between 3000:8000, excluding ports that are blocked by Google Chrome for being considered unsafe: 3659, 4045, 5060, 5061, 6000, 6566, 6665:6669 and 6697. Up to twenty random ports will be tried.
