/*
Application for a tvguide grid display

VERSION 1.001


GridApp object manages the sub-objects used to store listings data (and displaying the data), along with
communicating with the server PHP script via Ajax commands (where the response is formatted as JSON and converted
into objects)

Hierarchy
---------

	GridApp
		Grid						- EPG shown in a timeline grid format (time horizontally; channels vertically)
			Schedule				- Manages the PVR recording schedule (shown as timeline bars above the channels)
			Chans					- Manages a single channel (i.e. a row in the grid)
				Recording			- Wraps up a Prog with recording (or not) info
					Prog			- A single program
		RecList						- Recording list: requested recordings & actual scheduled program recordings shown as a table
			Recording				- Wraps up a Prog with recording (or not) info (Amended for RecList)
				Prog				- A single program (Amended for RecList)
		

Settings
--------

Settings are sent from the PHP as a settings object that initialises GridApp. GridApp then passes this information
down the hierarchy (i.e. it passes this to Grid & RecList, which in turn pass the settings down to their sub-objects)
