/**
* Quick include template plug-in
*
* Like {@link smarty_compiler_foreachq() foreachq}, this plug-in has been written to provide
* a faster version of an already existing Smarty function. <var>includeq</var> can be used
* as a replacement for the Smarty
* {@link http://smarty.php.net/manual/en/language.function.include.php include} function as long
* as you are aware of the differences between them.
*
* Normally, when you include a template, Smarty does the following:
* - Backup all your template variables in an array
* - Include the template you specified
* - Restore the template variables from the previously created backup array
*
* The advantage of this method is that it makes the main template variables <i>safe</i>: if your
* main template uses a variable called <var>$stuff</var> and the included template modifies it
* value, the main template will recover the original value automatically.
*
* While this can be useful in some cases (for example, when you include templates you have absolutely
* no control over), some may consider this a limitation and it has the disadvantage of slowing down
* the inclusion mechanism a lot.
*
* <var>includeq</var> fixes that: the code it generates doesn't contain the variables backup/recovery
* mechanism and thus makes templates inclusion faster. Note that however, this new behavior may
* create problems in some cases (but you can prevent them most of the times, for example by always
* using a <var>tmp_</var> prefix for the variables you create in included templates looping sections).
* @param $tag_args
* @param $comp
* @return string
