/**
* Abstract class representing the result of decoding a barcode, as more than
* a String -- as some type of structured data. This might be a subclass which represents
* a URL, or an e-mail address. parseResult() will turn a raw
* decoded string into the most appropriate type of structured representation.
*
* Thanks to Jeff Griffin for proposing rewrite of these classes that relies less
* on exception-based mechanisms during parsing.
