* feat: initial wandb configured. Sweep parameters aren't configured yet. * feat: Wandb logs now results. * feat: gitignore. * fix: Took out print() * feat: Changed default value of wandb to False. * feat: Added wandb to turn of automatically if there is no environment variable to start it (when we push it). Added environment configuration aswell. * feat: Each assets model is seperated into a run that tracks the results. * fix: Nonetype error, truncated assets. * fix: Fixed the logging to wandb.
