Examples unclear (room for docs!)

[AlbinoGeek]

Hello there!

It is unclear within some examples how the "Template Name" is being set.

While it is very obvious in the simple example:

multitemplate/example/simple/example.go

Lines 10 to 11 in 4955c93

	r.AddFromFiles("index", "templates/base.html", "templates/index.html")
	r.AddFromFiles("article", "templates/base.html", "templates/index.html", "templates/article.html")

It is not so obvious within the advanced example:

multitemplate/example/advanced/example.go

Line 45 in 4955c93

r.AddFromFiles(filepath.Base(include), files...)

And is further confused within the multibase example:

multitemplate/example/multibase/example.go

Line 45 in 4955c93

r.AddFromFiles(filepath.Base(article), files...)

multitemplate/example/multibase/example.go

Line 63 in 4955c93

r.AddFromFiles(filepath.Base(admin), files...)

(Not to mention the name conflicts possible within the multibase example, covered in another issue.)
