Review request for Michael Stack and Jonathan Gray.


Changes
-------

added licence; fixed dir name; removed a tab.


Summary
-------

Test deliberately creates a table with blocksize = 1Byte (so that each KV is a block of its
own).
The getData() calls all take a last argument which is the number of expected blocks read.
Those numbers are the current baseline. I'll hope to submit patches for hbase-4433 & hbase-4434
in the next day or so, and at that time these counts should go down.


This addresses bug HBASE-4450.

> Add a simple test for number of blocks read. The tests intent is to serve as baseline
for expected blocks read and for catching regressions. As optimizations for HBase-4433 or
Hbase-4434 are committed, the test would need to be updated to adjust the counts for expected
blocks read in various cases.
