parse method

@override SMSParsedResult? parse(Result result)

Attempts to parse the raw Result's contents as a particular type of information (email, URL, etc.) and return a ParsedResult encapsulating the result of parsing.

@param theResult the raw Result to parse @return ParsedResult encapsulating the parsing result

Implementation
