/**
 * Payment module by BoonEx
 *
 * This module is needed to work with payment providers and organize the process
 * of some item purchasing. Shopping Cart and Orders Manager are included.
 *
 * Integration notes:
 * To integrate your module with this one, you need:
 * 1. Get 'Add To Cart' button using serviceGetAddToCartLink service.
 * 2. Add info about your module in the 'bx_pmt_modules' table.
 * 3. Realize the following service methods in your Module class.
 *   a. serviceGetItems($iSellerId) - Is used in Orders Administration to get all products of the requested seller(vendor).
 *   b. serviceGetCartItem($iClientId, $iItemId) - Is used in Shopping Cart to get one product by specified id.
 *   c. serviceRegisterCartItem($iClientId, $iSellerId, $iItemId, $iItemCount, $sOrderId) - Register purchased product.
 *   d. serviceUnregisterCartItem($iClientId, $iSellerId, $iItemId, $iItemCount, $sOrderId) - Unregister the product purchased earlier.
 * @see You may see an example of integration in Membership module.
 *
 *
 * Profile's Wall:
 * no spy events
 *
 *
 *
 * Spy:
 * no spy events

 *
 * Memberships/ACL:
 * Doesn't depend on user's membership.

 * @see BxPmtModule::serviceGetAddToCartLink
 * BxDolService::call('payment', 'get_add_to_cart_link', array($iSellerId, $mixedModuleId, $iItemId, $iItemCount));
 *
 * Check transaction(s) in database which satisty all conditions.
 * @see BxPmtModule::serviceGetTransactionsInfo
 * BxDolService::call('payment', 'get_transactions_info', array($aConditions));
 *
 * Get total count of items in Shopping Cart.
 * @see BxPmtModule::serviceGetCartItemsCount
 * BxDolService::call('payment', 'get_cart_items_count', array($iUserId, $iOldCount));
 * @note is needed for internal usage(integration with member tool bar).
