I have been considering the approach we should take here.

The documents from https://github.com/plotly/plotlyjs.jl-docs/tree/master/julia should be included in a new documentation section called 'Tutorials'.

We can organise them into sub-categories in a later PR following the arrangement shown at https://plotly.com/julia/

Each file should have a new commented header, something like

Suggested change

	"Extra Examples" => [
	"Tutorials" => [

I would keep the examples mostly as they are, but I think this should be under 'Tutorials' (aka extra-examples). Can line_scatter2.md and line-and-scatter.md be combined?
