User test how well / how easy it is to install and begin to use Web-Map-Custom-Element

This relates to #427, because it should be painless to install and start to use <mapml-viewer> etc., but I won't believe it until we test the theory with real users.

How quickly can you make a map without aggravation, along the lines suggested by this tutorial, from scratch, using this npm package.

• Tutorial provided on government website fails to load in map (Status Code 404). Most likely due to src link of script tag.
• map-coordinates tag (longitude, latitude) order may be confusing to users since english convention order is flipped (latitude, longitude).
• Standard method to modifying mapml map size should be documented.

As a beginner to HTML I found the tutorial very helpful and easy to follow as first steps into the world of HTML. Some changes I would make to improve the document are; add links to other free HTML resources as mention at the start of the tutorial, and I also find the wording of the document somewhat confusing in some paragraphs. Overall I think the tutorial does its job and taught me, in a simple way, the basics of HTML.
