Simple, zero-dependency, Node.js version of https://github.com/akamai/dnsperf for measuring DNS server throughput and latency.

Limitations:

• There's no CLI parser yet -- instead you need to modify the first few lines of dnsperf.js.
• Only a few parameters are supported. PRs welcome to add more of dnsperf's features. (Please try to avoid adding dependencies though.)

The reported statistics are on-par with dnssec's reported statistics.
