/***************** GenericCalendar Instruction ******************/
	/*   GenericCalendar class is a class made to easily be used for 
	 *	different calendars. It allows for custom week and day 
	 *	templates to make the calendar look and do what you like.
	 *	GenericCalendar has abstract method(s) that MUST be overridden, 
	 *	whether used or not. Below is a list of helper functions that 
	 *	can be used in your implementations of functions.
	 *
	 *TEMPLATES (code supplies generic templates, can be overridden):
	 *	weekBeginTemplate() - called when a week starts (after saturday)
	 *	weekEndTemplate() - called when a week ends (before sunday)
	 *	dayTemplate() - called for each day in the given month
	 *	offDayTemplate() - called for each day in the previous and 
	 *		following months that occurs in the calendar
	 *	dayLegendTemplate() - called for Sunday, Monday, ... legend
	 *
	 *DEFAULT CSS CLASSES:
	 *	day - day of the week
	 *	off-day - day of the week for previous, following months
	 *	weekend - Saturday and Sunday
	 *	date - date of calendar square
	 *	day-legend - div that holds Sunday, Monday, ... divs in the legend
	 * 
	 *ABSTRACT FUNCTION(S) (must be overridden): 
	 *  - abstract public function gatherData()
	 *		This function is not required, but is a good spot to do
	 *		all the necessary calculations and build a 2d array 
	 *		that contains data that will be passed to 
	 *		GenericCalendar::fillData(). see fillData for more info.
	 *
	 *HELPER FUNCTIONS/VARIABLES:
	 *	Month Information (accessed using $this->exampleFuncName()):
	 *		GenericCalendar->allDays (accessed by $this->allDays) 1D array of Day objects.
	 *		public function getMonthNum() returns 1 for Jan, 2 for Feb, etc.
	 *		public function getMonthName()
	 *		public function getDaysInMonth() return number of days in current month
	 *		public function getPreviousMonthNum() same as getMonthNum, but for previous month
	 *		public function getPreviousMonthName()
	 *		public function getPreviousMonthYear()
	 *		public function getNextMonthNum()
	 *		public function getNextMonthName()
	 *		public function getNextMonthYear()
	 *	Print Functions:
	 *		public function printDaysBefore() prints the days of the previous month
	 *		public function printDaysAfter() - see above. uses css class "off-day"
	 *	Day Information (accessed using a Day object i.e. $dayObj->exampleFuncName ):
	 *		Day->data (Days can be accessed through the GenericCalendar->allDays array)
	 *			1D array of data to be printed in the dayTemplate. 
	 *		public function getName()
	 *		public function getDate()
	 *		public function getIsWeekendString() return ' weekend' if day is a sat or sun
	 *		public function getIsTodayString() returns ' today' if the date is todays date
	 *
	 *OTHER FUNCTION(S):
	 *  public function printCalendar() 
	 *  	GenericCalendar provides a printCalendar() function, but 
	 *		it may very well be overwritten. It is recommended that 
	 *		printCalendar() calls seperate template functions for day, 
	 *		weekBegin and weekEnd using the appropriate data. These 
	 *		template functions may be methods in your implementation 
	 *		of GenericCalendar
	 *
	 *	public function fillData()
	 *		Takes an array of arrays and fills the appropriate days in 
	 *		the calendar with the information in the given day. 
	 *		Example:
	 *		$yourData = array(
	 *			2 => array("go to the gym", "make dinner"),
	 			7 => array("file taxes"),
				13 => array("look at this website: 
								<a href='http://www.google.com'>Google</a>", 
							"call mom at 9:30am", 
							"go for a run")
	 *		);
	 *		$yourCalName->fillData($myData);
	 *		With the proper printCalendar function, the given strings 
	 *		will be printed on the 2nd, the 7th, and the 13th days respectively. 
	 *		HTML is allowed within the strings if it works within PHP strings.
	 *
	 *	See associated example file (can be found at www.teastburn.com) for more information.
