User-friendly time-dependent notebook

[bclyons12]

Before we do the experimental tutorial, it would be good to clean it up to make it user friendly. Some requested changes. Preferably these should all be inside the notebook, no changes to FUSE, so we don't need to release and reinstall the sysimage.

• Obvious identification of code users should touch and what they shouldn't.
• A flag that transitions between :predictive and :analysis mode, with if statements to setup act properly for each.
• Some markdown documentation with basic guidance, while still looking like a working notebook not a tutorial.
