logs6:Make RL model work with small model

Make RL model work with small model 2018/04/18

• Log 1: what specific output am I working on right now?
  • Make it possible RL model run with small models, so that we can save time.
• Log 2: thinking out loud - e.g. hypotheses about the current problem, what to work on next
  • first we should extract parameters for the training loop, so that we can run it with hparams
  • make it run with mode == Test
• Log 3: record of currently ongoing runs along with a short reminder of what question each run is supposed to answer
  • should commit the change first
  • Should have graphs here and think about next steps.
  • 
  • 
  • 
• Log 4: results of runs (TensorBoard graphs, any other significant observations), separated by type of run (e.g. by environment the agent is being trained in)
