Add support for cmd args

[luminosuslight]

Working:

• node commandline arguments
• v8 commandline arguments

Closes #22.

Can we move this into a member function (constructor?) of the CmdArgs class?

[luminosuslight]

Good point!

another Todo: test uv args.

It seems like a function func(std::initializer_list<std::string> l) needs to be called as func({"foo", "bar"}) (with curly braces, see http://en.cppreference.com/w/cpp/utility/initializer_list). This means that it makes no difference whether vector or initializer_list is used.

What else did you/we expect?

These two don't need to be public.

👍

Technically, it's not really a "static" variable, is it? Looks like a simple member variable to me.

[luminosuslight]

right, I fixed the documentation

It would be cool if you could call it as func("foo", "bar") instead of with curly braces, but it seems like this is only possible with real variadic functions or recursive templates (which would be hard to maintain in this case).
