	 * Custom PostMessage Convetions Followed - Sending and Receieving data gracefully
	 * -------------------------------------------------------------------------------
	 *
	 * 1. First convetion
	      Since data can be sent or receieved via postmessge API in the form of strings,
	      the library stores data as stringified JSON object and while reading it, parses the JSON stringified earlier.
	      This is easy to maintain and deal with data.
	
	 * 2. Second Convetions
	      With every data, there's an associated message identifier.
	      A message identifier helps in knowing the intention of what event actually is for.
	      For eg: To send data after proper establishment from Child tab,
	      Parent tab acknowledges the connection by returning the true identity of the Child tab.
	      This is done via prepending the Event name i.e. HANDSHAKE_WTIH_PARENT
	
	      So the postmessage's message would like: `HANDSHAKE_WTIH_PARENT{"id": 123, "name": "Hello World!"}`.
	      So, while reading the message, it has to be first checked up with the defined event names
	      and then after successful match, the message is split using the Event-name as a delimiter.
	      The first entry if the event name and the second one is the actual data.
