Issue 86

Please review these bulk compute test cases, i have updated them according to java doc. Let me know what changes are needed. Thanks
It looks like there are too many assertions, this test verifies different things.

I understand those assertions as
 - when the iterable (returned by the function provided to the method) doesn't contain a key that is present in the store, the store value is not changed.
- the iterable changes the value in the store for the key(s) it returns
- the map (returned by the method) contains the K,V pairs of the iterable and the store

What part(s) of the javadoc does this test refer to?
