+     This observer waits for storage updates like new image added or notes received. 
+     It then checks in the loadBuffer to see if there is a view waiting for this update in loadBuffer, if yes, it loads it up and remove the waiting entry.
+     loadBuffer stores key-value pair with viewTag as a key and slideIndex as value. 
+     For the same view, we only keep the last requested slide index on the waiting list.
+     It is thus indispensable to identify each view with an unique tag in its view controller. Here we use 0-10 to indentify central vc views and 11-N for swipe-in tableViewController which allows direct slide number change. 
+     We handle lecturer's notes at the same time as an entry in the load buffer via an instrospection.
