Can't import the newSettings function qualified
The following code 
```nim
import jester except newSettings, settings

router myRouter:
  get "/library":
    resp "library"

when isMainModule:

  let mySettings = jester.newSettings(
    port=Port(7000)
  )

  var jesterInstance = initJester(myRouter, mySettings)
  serve(jesterInstance)
```

fails to compile with
```
/tmp/test.nim(4, 8) template/generic instantiation of `router` from here
/home/andrew/projects/jester/jester.nim(831, 20) Error: undeclared identifier: 'newSettings'
```

The issue seems to be fixed with this commit https://github.com/AjBreidenbach/jester/commit/2c58c0e72e8df28ae76c330e1718ddf4aa070287
