Scala maps
//create a map
val cars = Map("james" -> "BMW", "ike" -> "Infiniti", "stephen" -> "Buick")
//create a map from an Array
//Scala does not provide a convenience method to do this... :(
val carArray = Array("james", "BMW", "ike", "Infiniti", "stephen", "Buick")
val cars = carArray.grouped(2).toList.map(c => (c.head,c.last)).toMap
//mapping over a map
//transform all string keys to symbols (interned strings)
