This container allows iteration of the parameter list in an HTTP extension. The parameter list is a series of name/value pairs with each pair starting with a semicolon. The value is optional. If a parsing error is encountered while iterating the string, the behavior of the container will be as if a string containing only characters up to but excluding the first invalid character was used to construct the list.
param-list = *( OWS ";" OWS param ) param = token OWS [ "=" OWS ( token / quoted-string ) ]
          To use this class, construct with the string to be parsed and then use
          begin and end, or range-for to iterate each
          item:
        
for(auto const& param : param_list{";level=9;no_context_takeover;bits=15"}) { std::cout << ";" << param.first; if(! param.second.empty()) std::cout << "=" << param.second; std::cout << "\n"; }
The first element of the pair is the extension token, and the second element of the pair is an iterable container holding the extension's name/value parameters.
