Detailed Description

template<class PAT, template< typename > class ALLOC, class VAT>
class storage_manager< PAT, VAT, ALLOC, file_storage >

Storage Manager class partially specialized to File-based Storage manager to stores VAT in predefined-size buffer and uses a binary file for swapping in/out vats.

An object store. Specifically we want to store VATs and their associated patterns. It provides routines to find/access/store VATs with a pattern key.
