v0.9.5-beta

This release features enhanced concurrency control and more attention to useability. Hermes now provides dynamic data structures, which avoids forcing users to configure strict limits on data structures such as Buckets and VBuckets for the sake of simplicity, reducing accidental segfaults due to misconfiguration. In addition, these data structures reduce the complexity of extending Hermes to support new policies, such as Data Placement Engines and Prefetchers.
