The missing std::string::split() function

std::string::split.cpp

vector<string> split(const string &str, const char delim = ' ') {
  stringstream ss(str);
  vector<string> strvec;
  
  string tmp;
  while (std::getline(str, tmp, delim))
    strvec.push_back(tmp);
  
  return strvec; // std::move()
}
