HTTP.@register macro is removed, handler is not defined

Thanks for the tutorial! It seems that in the last three years the @register macro has been removed and replaced with a function named register!. Docs at

https://juliaweb.github.io/HTTP.jl/v0.6/index.html#HTTP.Handlers.register!

This seems to fix any syntax errors to use the module in dev mode and start a server.

Now creating an object through the client module fails with the following exception.

julia> alb1 = Client.createAlbum("Free Yourself Up", "Lake Street Dive", 2018, ["Baby Don't Leave Me Alone With My Thoughts", "Good Kisser"])
