Subproduct for file product solution

After playing with it for a while I realized that a few features, that are currently missing, could have made my life much easier. So I decided to give it a try, and incorporate those features. All features are configurable (admin/ecsettings/subproducts under advanced), and disabled by default, which means that they do not change the module behavior unless turned on.

1. File Product Friendly: File subproduct, by definition, implies different file per variation, hence I added the ability to change file-subproduct name and price during subproduct creation.
2. Invisible Subproducts: Make subproducts invisible (also unpublished) to the user (i.e. in taxonomy, search results, etc.). Purchased could only be done via parent product.
3. Add Price to Options: Add price to subproduct drop down menu options. Goes hand in hand with Invisible Subproducts.

Hope it helps

Found a petit bug, herein the fix

Try adding next line to your theme
print_r($node->content['subproduct_options']['#value']);

np, in your theme, add it into node.tpl.php or node-<node type, like video, music, etc.>.tpl.php (i.e. node-video.tpl.php)

To get a sense of it you can try garland, for instance, and in node.tpl.php change: <div class="content"> <?php print $content

to: <div class="content"> print_r($node->content['subproduct_options']['#value']); </div>
