> The current implementation does this by returning an instance of:
> LevelDbRangeIterator.
> This custom iterator implements the range (from, to) by only guarding the
> hasNext function. This means that as long as the caller calls hasNext before
> a next, everything will work fine.
> However, if the caller invokes next() directly, then the range is not obeyed.
> Essentially, we can retrieve elements beyond the specified range (all the way
> to the end).
> I tested this by tweaking testRange function of TestKeyValueStores
> - Get an iterator over a defined range (f to u)
> - Display all the values using only iter.next (until we get an exception)
> This method printed all the values from 'f' to 'z' instead of 'f' to 'u'
