Downloads a file from Dropbox

drop_get(
  path = NULL,
  local_file = NULL,
  overwrite = FALSE,
  verbose = FALSE,
  progress = FALSE,
  dtoken = get_dropbox_token()
)

`path`	Path in the user's Dropbox, relative to root
`local_file`	The name of the local copy. Leave this blank if you're fine with the original name.
`overwrite`	Default is `FALSE` but can be set to `TRUE`.
`verbose`	By default verbose output is `FALSE`. Set to `TRUE` if you need to troubleshoot any output or grab additional parameters.
`progress`	Progress bars are turned off by default. Set to `TRUE` ot turn this on. Progress is only reported when file sizes are known. Otherwise just bytes downloaded.
`dtoken`	The Dropbox token generated by `drop_auth`. rdrop2 will try to automatically locate your local credential cache and use them. However, if the credentials are not found, the function will initiate a new authentication request. You can override this in `drop_auth` by pointing to a different location where your credentials are stored.
