/**
* Build product collection
* @param int $storeId Store id
* @return Mage_Catalog_Model_Resource_Product_Collection
*
* The collection is formed thus:
* 1. Since we are working with multiple stores, we use Mage:getResourceModel('catalog/product_collection') instead of
* Mage::getModel('catalog/product')->getCollection() because the latter will load some store context we
* prefer to control explicitly.
* 2. setStore() is a method that will set up store context we do need. It does not set filtering.
* 3. addAttributeToSelect() to get only the fields we need. Each product's _data will contain only these fields.
* 4. addFieldToFilter() basically our 'where' clauses
* 5. addStoreFilter() called without arguments defaults to the store most recently setStore()'d. Admin store is explicitly
* ignored by addStoreFilter().
* 6. setPageSize() in order to limit collection's use of memory. This is the number of products we'll load at once.
