Add stats collection and pert tests for batch methods

Since we have PR #244 it will be nice to collect
statistics for batch operations too.
To establish the effectiveness of `crud.batch_insert()`
method compared to `crud.insert()`, perf tests were added.
`crud.insert()` in the loop and `crud.batch_insert()`
are compared for different batch sizes.

Closes #193
