  Create a new StringArrayPropertyEditor with the given separator.

  Parameters:
    `separator` - the separator to use for splitting a `String`
    `emptyArrayAsNull` - `true` if an empty String array is to be transformed into `null`

### StringArrayPropertyEditor

    public StringArrayPropertyEditor(String separator,
                                     boolean emptyArrayAsNull,
