Needs to have better command line experience

[BrendanBenshoof]

I think we should implement argparse to handle command line arguments.

we need to handle:

• just start and connect to default bootstrap, dont ask me questions
• use a given public address
• use a given bind address
• use ipv4, ipv6, or both (gonna be fun get the public ipv6 address)
• use a given bootsrapt peer

It might be worth rotating this into a configuration file, so use it more like:

python main.py -config configfile.json

A few thoughts:

• We probably shouldn't have a bootstrap server hardcoded into the code. Instead, it should live either in a configuration file or some sort of "meta" file a la bittorrent.
• For users behind a NAT (that is, most of them), we need a way to detect this. Our getmyIP endpoint can help, and we can print a line to stdout and/or the log file to warn them to open the appropriate port.
• For users not behind a NAT (likely users running on a server with a firewall enabled), should we have a method that the bootstrap node(s) use to detect this and warn the node to open their port (e.g. the node reports the IP/port it's using to the bootstrap, then the bootstrap tries to connect back and reports an error if the port can't be reached)?
• Should we run one server that listens on IPv4 and IPv6? If so, should it still be considered 2 nodes or should it be 1 node with >1 IP/port?
• Should we use the standard dotfile for configurations on Linux/Unix/Mac machines? How should we handle this on other platforms?

argparse, once you work through it, is actually really REALLY nice

At least the C version is. I used it in the last CUDA project. It had a steep learning curve but it saved me a huge hassle later when I went to tack on, mutate, munge, etc command line args randomly to do wacky things on the spot.

Right now the server runs off a config file.

What we could still use is a command line tool to manage the server and utilize the dht (read,write, check status, add peers manually, ect)
