Defaults to no caching. A simple bounded cache implementation using ConcurrentHashMap is provided (CHMCache). When caching is applied, ContainerNodes are always deep-copied. This way the cached instances remain immutable.
Even with a very modest cache size, this yields a good hit-rate and a major speedup (~3x on the low-level benchmark, ~2x on the high-level API) along with a significant reduction in object churn (refs #13).
