I agree to make HasSeed the main API to decide whether an algorithm takes a seed.
I propose to make Pipeline extends from HasSeed and users can setSeed for the whole pipeline. After users setting seed for the pipeline, it will pass to all meta-algs who implemented HasSeed.
Then we can have reproducible results for entire pipelines. Please correct me if I have some misunderstands.
