-----------------------------------

Hi [~lewismc] , [~renato2099]

Thanks for your help.

I have been working on my fork and I would highly appreciate if you can check the changes
I have done.

1. I added the size() function into the 'easy' backends ([Commit 1|https://github.com/carlosrmng/gora/commit/76cc89cddd2cbda42518de8e304e92e3f341a744])

2. I used the limit attribute of Query to set the batch size in Accumulo, Avro and HBase,
so 'this.limit' could be used for implementing size() on those backends. ([Commit 2|https://github.com/carlosrmng/gora/commit/0ee48ab3d96445a280852a1fd04206efb883baa9])

Also, I was wondering where should I add a test for this new function? I was thinking I could
add a test in 'DataStoreTestBase', so it could be reused for all the backends.

> Right now we iterate through results by doing

> while (results.next()) {
>    ...

> {code}
> It is a pain to always require a counter of sorts and would be much more intuitive to
provide a simple #size() method.
