Class Rowset

Implements a rowset that supports row change logging and CRUD operations. Rowsets are not optimal for data replication as they perform linear search which is slow, however Rowset class supports sorting. In contrast, Tables are kind of rowsets that keep data pre-sorted by key thus facilitating quick searching
