Workflow improvement suggestions #116

I really like using smart_dispatch and I have a few ideas how it could be improved:

• The location for creating logs should configurable, now SMART_DISPATCH_LOGS seems to be hardcoded.
• The names of the log folder in SMART_DISPATCH_LOGS should be configurable. When I run my 99th experiment it becomes quite hard to enter the path to its folder with logs. Would be cool to be able to do smth like

smart_dispatch.py -n my_experiment_with_batch_norm

which could create a folder SMART_DISPATCH_LOGS/my_experiment_with_batch_norm

• The by far most important deliverables of a launch are .err and .out files. I think they should have simpler names (now their names contain some kind of a hash) and that they should be in the top-level folder, not in /logs.
• I think that the default current directory for the launched job should be not the home folder, but rather SMART_DISPATCH_LOGS/my_experiment_.... This would be very helpful when one wants to repeat an experiment multiple times but is too lazy to invent a handful of different names for experiments of the series.

So far this it it, maybe more is coming.
