example usage:

var nn = require('nanomsg.node')
, pub = nn.socket(nn.AF_SP, nn.NN_PUB)
, sub = nn.socket(nn.AF_SP, nn.NN_SUB);

nn.bind(pub, "tcp://127.0.0.1:7788");
nn.connect(sub, "tcp://127.0.0.1:7788");
nn.usleep(4000); // 4 ms

nn.send(pub, "Hello from nanomsg!");

console.log("received: " + nn.recv(sub));

nn.bind(socket, address): bind to address
nn.connect(socket, address): connect to address
nn.send(socket, message): send message to socket(message is binary safe)
nn.recv(socket): recv message from socket(return binary safe message string)
nn.errno(): get errno
nn.strerror(errno): get error string
nn.setsockopt(socket, level, option, optval): set socket option(all arguments must be integer)
nn.getsockopt(socket, level, option): get socket option(all arguments must be integer)
