Google rich snippets - 13,000+ downloads, 5* rating

Rich Snippets are a way to provide Google detailed product information in a structured way so that in search results it can display rich snippets (for example, price, availability, and review ratings) Sample:  Rich snippets help you to: Attract potential buyers while they are searching for items to buy on Google. Submit your product listings for free. Control your product information. You can maintain the accuracy and freshness of your product information, so your customers find the relevant, current items they're looking for. One issue with OpenCart's default aggregate rating is that it truncates the fraction instead of rounding it off. So if your aggregate rating is 4.9 (i.e. anything less than perfect 5 but more than 4), then OpenCart shows rating as 4 and 4 stars. This is not good or fair as your customers might think that average rating is lower than it is. But it's even worse if you are using Rich Snippets because then this lower than real rating shows on Google results page.  So, an additional task that this extension performs from v 1.8 onwards is that it fixes the ratings. With this extension, your shop shows stars based on rounded off average rating, and Google is provided accurate average rating, which seems more realistic to Google and will help your Rich Snippet show up more quickly in results, and not be snippet-spam flagged. Tooltips are also added to rating stars. Because this is a vQmod, no core files are touched, and the changes should carry over to the next version.
