Cache Warmup Example
Renders the template code inside this tag with default variables
when the template is compiled. Demonstrated by assigning a new
variable which is NOT set by the View and using this variable to
render a section with a dynamic name (which would fail if no
variable exists).
Expected result:
This template file can be warmed up without rendering it via the
`example_cachewarmup.php` file even though it depends on a
variable normally only assigned from that file.
Warmup-exclusive variable assignment worked!
