Detailed Description

A nocommentstream is an istream that strips '#' comments.

All characters following (and including) a '#' are ignored up to (but not including) the next newline character.

Example usage:

 std::ifstream ifs("config.txt");
 if (!ifs)
   throw std::runtime_error("config.txt: cannot open");
 Dv::Util::nocommentstream nocifs(ifs);
 std::string line;
 while ( std::getline(nocifs, line) ) {
   // line does not contain comments
   }
