This class can be instantiated by passing in the Redis connection and base name. After that it works the same as ConditionalFreqDist as shown in the code below:
0  1 1 [`cond1`]
How does this work?
RedisConditionalHashFreqDist also defines a clear () method. This is a helper method that calls clear () on all internal RedisHashFreqDist instances. The clear () method is not defined in ConditionalFreqDist .
