Detailed Description

template<class Val, class SV>
class bm::rsc_sparse_vector< Val, SV >::back_insert_iterator

Back insert iterator implements buffered insert, faster than generic access assignment.

Limitations for buffered inserter:

Do not use more than one inserter per vector at a time
Use method flush() at the end to send the rest of accumulated buffer flush is happening automatically on destruction, but if flush produces an exception (for whatever reason) it will be an exception in destructor. As such, explicit flush() is safer way to finilize the sparse vector load.
