[mullerhai]

Hi sbrunk:
storch is powerful ,inspire storch some best code style and framework, now I have rewrite some code for storch to extend it feature make it similar like pytorch more, I add recommend some layer and model ,graph compute like gcn gat, some layer lstm gru rnn, some dataset dataloader sampler ,and make it can train torch model on spark and deploy torch model on flink realtime stream.
I think storch will be popular on jvm java/scala/kotlin in future.

I think I need pull my code merge with your storch github repo after I test all new feature , then I think I will push storch every module to maven ivy sbt public reposity make everyone use storch convient
