Questions related to the ExpressionEngine "templating" system.

In ExpressionEngine, a template is effectively taking the place of a page on a site and when rendered displays content from modules and plugins. Whenever a page is requested within an ExpressionEngine site, the system calls the Template class to discover which template is being requested and then does all of the parsing and processing required for rendering the template. This processing includes the embedding of other templates, tag and template caching, PHP processing, and it performs the calling of modules and plugins when their tags are found in the template.
