Better example naming

[PabRod]

Problem

The example names are not very transparent.

Solution

Give them descriptive names, such as:

Example1.jl -> 01-Logistic.jl

Notes

This will require a modification in make_examples.jl:

using Literate
using Glob

cd("examples")

#files = glob("Example*jl")
files = glob(*.jl)

for f in files
    println("MD for $(f)")
    Literate.markdown(
        f ;
        flavor = Literate.CommonMarkFlavor(),
        codefence = "```julia" => "```",
    )
    println("NB for $(f)")
    Literate.notebook(f ; execute = false)
end
