+/**
+ * This code contains abstract stacked item. Main goal of this is to make items dropping from storages, smartfridges, etc. not lag the clients out.
+ * It is, as simple is possible, tries to implement stacked items behavior like in storages.
+ * Main features:
+ * - Items appear stacked when dropped from smartfridge on destruction or when amount taken at one time is too high
+ * - Same rule applies to bags or storages with display_contents_with_number and allow_quick_empty properties enabled
+ * - Can't be taken by hand. Instead, player takes one sample from entire stack.
+ * - Same rule applies to pulling. Player pulls only one sample from entire stack.
+ * - Player can walk over stack.
+ * - Integrity of stack is determenied by summary of stacked items.
+ * - One by one items are deleted from stack if stack is damaged by integrity of one stack item.
