extends GenericPatternCache

This class is a GenericPatternCache subclass implementing a random cache replacement policy. In other words, patterns are added to the cache until it becomes full. Once the cache is full, when a new pattern is added to the cache, it replaces a randomly selected pattern in the cache.
