v2

I never really liked the interface of v1, so after coming back to this project, I spent some time thinking about how it could be improved, took some inspiration from Golangs flag module, and made v2, which has a simpler, more flexible interface with better type safety

For example:

• It doesn't cast char* to uint64_t and require you to cast it back
• It doesn't require you to create a parser object, you just call parse
• You don't have to add the arguments to that parser object, it's taken care of just by calling the constructor
• You aren't required to provide descriptions for you program and every argument

That last one means that v2 will not take care of --help and -h for you. If you want a help menu, you have to create it yourself. But help menus aren't always required and when you do want one, this gives you control over what it looks like

How do I use this

Check out test.cpp. It demonstrates the full scope of this library
