LabelCache

```
public class LabelCache
extends java.lang.Object
```
A top-level cache for label and policy objects, allowing us to intern Label, ConfPolicy, and IntegPolicy objects. Because this cache is top-level (i.e., it exists outside of transactions), it is separate from SecurityCache, which is a per-transaction cache. This class is thread-safe and is kept in the fabric.lang.security package to ensure that only security-related classes can modify this cache.
