Zict: Composable Mutable Mappings

The dictionary / mutable mapping interface is powerful and multi-faceted.

• We store data in different locations such as in-memory, on disk, in archive files, etc..
• We manage old data with different policies like LRU, random eviction, etc..
• We might encode or transform data as it arrives or departs the dictionary through compression, encoding, etc..

To this end we build abstract MutableMapping classes that consume and build on other MutableMappings. We can compose several of these with each other to form intuitive interfaces over complex storage systems policies.
