Basic Read Write

    import scalax.io.Resource

    val reader = new StringReader("hello")
    // the fromReader method is passed a reference to a reader
    // this means the Resource can only be used a single time
    // only do this if you are passed a resource from a method and have
    // no way of constructing the resource within the fromReader method.
    val in = Resource.fromReader(reader)

    val numVowels = in.chars.filter("aeiou" contains _).size

    // *BOOM!* the second use will result in an exception because
    // Resource does not have access to the construction of the reader
    // just the reference to a previously created reader
    val numNumbers = in.chars.filter('0' to '9' contains _)

    // If you need a code block to construct the resource consider the following pattern:
    val in2 = Resource.fromReader {
      val string = "hello"
      new StringReader(string)
    }
