 4. Start `./julialab`
 5. Install `BallAndBeam.jl` using command `Pkg.clone("https://gitlab.control.lth.se/processes/BallAndBeam.jl.git"); using BallAndBeam` Lots of packages will now be installed, this will take some time.
 6. Type `cp(Pkg.dir("BallAndBeam","src","FRTN35_lab1.jl"), "FRTN35_lab1.jl"); edit("FRTN35_lab1.jl")`. The script `FRTN35_lab1.jl` will now open in the chosen text editor, edit it while following the lab manual. If unsure about how a function works, type `?function_name` for help.
