// A mutable match of a phone number within a piece of text.
// Matches may be found using PhoneNumberUtil::FindNumbers.
//
// A match consists of the phone number as well as the start and end offsets of
// the corresponding subsequence of the searched text. Use raw_string() to
// obtain a copy of the matched subsequence.
//
// The following annotated example clarifies the relationship between the
// searched text, the match offsets, and the parsed number:
//
// string text = "Call me at +1 425 882-8080 for details.";
// const string country = "US";
//
// // Find the first phone number match:
// PhoneNumberMatcher matcher(text, country);
// if (matcher.HasNext()) {
// PhoneNumberMatch match;
// matcher.Next(&match);
// }
//
// // raw_string() contains the phone number as it appears in the text.
// "+1 425 882-8080" == match.raw_string();
//
// // start() and end() define the range of the matched subsequence.
// string subsequence = text.substr(match.start(), match.end());
// "+1 425 882-8080" == subsequence;
//
// // number() returns the the same result as PhoneNumberUtil::Parse()
// // invoked on raw_string().
// const PhoneNumberUtil& util = *PhoneNumberUtil::GetInstance();
// util.Parse(match.raw_string(), country).Equals(match.number());
//
// This class is a port of PhoneNumberMatch.java
