CAMP algorithm.

The algorithm is explained by the authors in CAMP: A Cost Adaptive Multi-Queue Eviction Policy for Key-Value Stores. This is a cost-aware cache policy, which takes into account the access times (i.e. the cost of recomputing or fetching the data). This is also a weighted policy, meaning it supports non-uniform entry sizes.
