a suggestion for package installation part

[kose-y]

Currently, most of the tutorials lead the readers to the Julia REPL to install packages. Wouldn't it be easier to install packages from the Pkg mode from the notebooks? A line beginning with ] runs a command in Pkg mode, just as how shell mode works in "In [2]" of IHT/Mendel_IHT_tutorial.ipynb. For example, we can use

]add https://github.com/OpenMendel/SnpArrays.jl

]add https://github.com/OpenMendel/MendelSearch.jl

]add https://github.com/OpenMendel/MendelBase.jl

]add https://github.com/biona001/MendelIHT.jl

]add DataFrames, Distributions, BenchmarkTools, Random, LinearAlgebra 

in separate cells to install the packages for the IHT tutorial.

Another possible approach would be beginning with using Pkg in Julia mode as in VCTest tutorial.
