Create directory to hold all YAML schedules for training baseline networks

The new directory 'examples/baseline_networks' contains YAML schedules
that we used to train the baseline networks for our experiments.
Theses scripts are currently scattered across the repository, so as a
first step I'm collecting them using softlinks.  Later we will physically
move these files to 'examples/baseline_networks', and remove the soft-links.
