accept vector<string> for argv

[sfinktah]

Because sometimes you don't have access to the command line arguments in their raw form...

std::vector<std::string> args;
int main(int argc, char** argv) {
   for (size_t i=0; i < argc; ++i)
      args.emplace_back(argv[0]);
   run_application();
}

void application() {
   auto cmdl = argh::parser(args);
   // ...
}
