====== Julia Software Install ======

For Julia software to run from the terminal app, the following environment variables must be set below
  ENV["LD_PRELOAD"]=
  ENV["LD_LIBRARY_PATH"]=
  ENV["JULIA_DEPOT_PATH"]="/home/USERNAME/.julia"
This will allow students to install additional Julia packages in their home folder under the .julia folder.
To set up a Julia kernel that allows central installation of packages do the following.
Start terminal app, set enivronment vars as above. Start Julia.  
  using Pkg
  Pkg.add("IJulia")
  IJulia.installkernel("julia-shared-1.8", env=Dict("LD_PRELOAD"=>"", "LD_LIBRARY_PATH"=>"","JULIA_DEPOT_PATH"=>"/home/.hub_local/.julia:/home/$USER/.julia"))
This will place the new Julia kernel in
  .local/share/jupyter/kernels/julia-shared-1.8
Will want to copy that folder to 
  cp -r .local/share/jupyter/kernels/julia-shared-1.8 /home/.hub_local/share/julia-kernels/.
Exit out of the terminal app. Then log off your JH instance and re-login in. It should now display a new
tile icon for the julia-shared-1.8.  For students to see the same tile icon they will need to run the following commands in the terminal app first
  mkdir -p .local/share/jupyter/kernels
  ln -s /home/.hub_local/share/julia-kernels/julia-shared-1.8 ~/.local/share/jupyter/kernels/.
Then they will also need to logout of their JH instance and log back in.
