Current implementation of library handles sending following requests
- Node Birth message

Node Birth/Device Birth and Data message have same format with change in contents of metrics.

var cid = "0c574252-31d5-4b76-bce6-53f2c56b544d";
var DataMessage = {
timestamp: 12345,
metrics: [{

}],
seq: 1
};
