Renaming and rearranging resources

[abkfenris]

Maybe a renaming/rearranging is in order at some point, so we have:

• Logistics
  • Getting Help
  • Preparation (link to various pages/guides)
    • Python/R learning resources
• Tutorials
• Projects
• Reference (how does the environment, work)
  • Git
  • Github
  • JupyterHub
  • Conda
• Guides (how to accomplish small specific tasks)
  • Git setup
  • Cloning tutorials
  • Git workflows
