Lines 1 to 6: The main.gsp page starts with <!doctype html>. This is an HTML5
doc type. Grails supports HTML5 out of the box.
Line 10: <g:layoutTitle> is used in layouts to render the contents of the title tag
of the decorated page. The <g:layoutTitle> tag substitutes the <title> from
the view that is being merged and links it in a style sheet and favicon that will be
used by all views.
Line 17: The <g:layoutHead> tag merges in the contents of the target view’s
<head> section. <g:layoutHead> is used in layouts to render the contents of the
head tag of the decorated page.
Line 22: <g:layoutBody> is used in layouts to output the contents of the body
tag of the decorated page. The <g:layoutBody> tag merges in the <body>
contents of the target view.
Line 25: <g:javascript> includes JavaScript libraries and scripts and provides
a shorthand for inline JavaScript. Specifying a library tells the Ajax tags which
JavaScript provider to use.
