If I look at the manner in which this class is instantiated and in the
manner in which the getColumnTypes method is invoked, I would either refactor
it into a helper class with only static methods and a private no args
constructor, or leave it like it is, but then add a constructor to it which
takes a `JSONObject` as an argument, so it doesn't need to be passed through in
all methods on the class.
