NEON tutorial suggestions

[wwieder]

• [x] list of CLM history files (plotting)
• [x] link at end of 1_getting started
• [x] shell commands in TEAK?
• [x] shorter parameter and namelist examples
• [x] break out spinup into new example
• [x] additional history variables
• [x] comparison between experimental and control simulations
• [ ] neon api rejects request if it gets too many requests at once.
• [x] download .csv files at end of tutorial 1?
• [x] Be sure to upload PRISM data, restart files, hist, eval, and datm data to the cloud (see /glade/scratch/wwieder/NEON_v2).
• [ ] CPER site 2021 PRISM data seems to have two files that are missing time dimension

[TeaganKing]

• [ ] clarify bash cells may need to be run with %%bash
• [ ] include some building block tutorials (eg, namelist modifications/output frequency or variables modifications would be useful outside of the FATES tutorial)
• [ ] fix run_neon.py '=!' vs 'is not' warning
• [x] add table of contents in readme
