 * Distributed cache for syncing state and data between Drillbits.

 * The distributed cache defined in this package can be used to make data

 * where most of the work of a given operation can be separated into independent
 * tasks, but some common information must be available to and mutable by all of
 * the nodes currently involved in the operation.
