Detailed Description
Quick API for atomically storing and retrieving collections of objects.
This is NOT scalable! Do not use for storage of lots of objects, or high performance, etc. This is a quick-and-dirty implementation for atomic storage of a small number of small objects.
Similar to BerkelyDB model: you can get and put objects based on a client- defined ID.
