String API

String column names are the easiest way to access data in DataFrame:

DataFrame.read("titanic.csv")
    .add("lastName") { "name"<String>().split(",").last() }
    .dropNulls("age")
    .filter {
        "survived"<Boolean>() &&
            "home"<String>().endsWith("NY") &&
            "age"<Int>() in 10..20
    }

The titanic.csv file could be found here.
