Examples of EvalError

com.google.refine.expr.EvalError
An error that occurs during the evaluation of an Evaluable. Errors are values, too because they can be stored in cells just like strings, numbers, etc. Errors are not thrown because an error might occupy just one element in an array and doesn't need to make the whole array erroneous.
