Detailed Description

Objects of this class are used to uniquely identifies a cache.

The UniqueCacheId is internally a std::pair<void*, std::type_index> which allows to exactly identify objects of any type. E.g. a class can use this to associate a cache to a tree object. Then other classes sharing the same tree but not knowing each other can share an evaluation cache for the tree (e.g. a ShapeFunctionCache<Tree>) by identifying the cache with a pointer to the tree. To avoid that an class and its first member are identified, the UniqueCacheId combines the void* with a std::type_index to also exactly fix the type.

This class is meant to be used with a CacheManager which will store the shared caches, identified via a UniqueCacheId.
