/**************************************************************************************************************************
	eventTable Script
	creates the table containing all scheduled events for the fiscal year
	Uses same external files as eventCalender primarily events.js
	External files:
		events.js - contains the event details for each event date
		global.js - contains the global variables used by this and other script files
		images - folder containing all image files
	 Functions
		preloadImages();	Preloads requested image files
		getFiscalYear():	Calculates and returns the current PAS fiscal year
		createCalTable(): 	Renders the table list of all PAS events

	Event file structure
	events[0] - Type ['P','V']
	events[1] - Month [1-12]
	events[2] - Day [1-31]
	events[3] - Year [nnnn] 
	events[4] - Time [nn:nn xM]
	events[5] - Fiscal Year [nnnn] Note: fiscal year is the four digits of the last year within the fiscal year
	events[6] - Description [X(28)]
	events[7] - Location [X(20)]

	Colors:
		#AAFFAA			Green - today's date
		#EFFFFF			Blue, light - event rows
		#6699CC			Blue - Calendar Header
		#F0F0F0			Grey, light - not used here
		#CCCCCC			Grey, medium - Weekday header
		#FAA61A			Orange - highlight clickable links
