# Election results

It's election night! Exciting! We have a feed of election results from a data supplier. They will supply us a file which will be updated throughout the night as results come in.

## Results format

The fields in the file will be separated by commas but each row will vary in length as described below.

A result will consist of:

val myFuture = someFuture // from a previous async op

val result = myFuture map { f =>
  slowOp(f) // either takes ages or doesn't complete at all
}

// then some timeout on result
timeout(result, fallback)

// question is: if fallback is used, what happens to the execution of the slowOp (does it continue and hog resources?!)

class UniversalSet[A] extends Set[A] {
  def contains(key: A) = true
  def iterator = throw new UnsupportedOperationException()
  def +(elem: A) = this
  def -(elem: A) = throw new UnsupportedOperationException()
  override def toString: String = "UniversalSet"

   * Convert a dataTable string representation into a List of Maps. For example:
   *
   *   | x | y      |
   *   | 1 | a is   |
   *   | 2 | b does |
   *
   * Becomes:

   *   List(Map(x -> 1, y -> "a is"), Map(x -> 2, y -> "b does"))
