Merge pull request #6 from dakrone/master

Makefile and bin/test hardening
Should have been hms.
Add timestamp to count output.

Useful for a quick calculation of indexing rate (for a 2m
refresh_interval):

% while true; do es count; sleep 120; done
10:45:24 10,567
10:47:27 12,416
10:49:28 14,772

Roughly 1k/min or 15/sec.
Use new name.
Add 'allocation' command
Add additional startup tuning
Document `es allocation` command
whoops, no longer using map-invert
Don't need quotes here.

Ignore tmp.
Alphabetical order.

Update license.
Use more modern version example.
