plugins should be specified in the final_config.yml
Currently, there is no way to know that a given plugin was used. At best we got an error telling that a given net (or any other plugin) was not found.
One of the fix is addressed by issue #71 , but it does not fix the fact that by looking at the config file, we should know which plugin were used.
I could be as simple as writing the command line used for training (and for preprocessing while we're at it), or just a list of plugin used.
