/*	MAP INITIALIZATION 
	The map is a Stylized Goole map centered on campus with a zoom of 16 by default.  Only the zoom control is turned on.
	
	In general KML files are used when there is nothing to display in the "Map Details" area (disabled parking, scooters, etc).
	JSON files are used when additional data needs to be displayed in the legend - with the major exception of the Parking layer
	
	KML Data
	The BUILDING layer comes from a KML file generated by kml/bldg.php 
	The GREEN SPACE layer comes from a KML file generated by kml/greenspace.php
	The PARKING layer comes froma  KML file generated by kml/parking.php
	The SCOOTER PARKING layer comes froma  KML file generated by kml/scooter.php
	The DISABLED PARKING layer comes froma  KML file generated by kml/dispark.php
	
	JSON Data
	Map SEARCH Functionality utilizes json/search.json which is generated by json/search.php - currently ONLY contains building data
	The DINING layer comes from a JSON file generated by json/dining.php
	The PERFORMING ARTS layer comes from a JSON file generated by json/perfarts.php

	and build an array (sched_bldgs) with the distinct buildings found in the schedule
	
	Once this is done it will locate the buildings on the map, place markers for each building and display the schedule in the map details box.

	SYSTEM ASSUMPTION: A class will never meet in more than 3 locations
	
	i = 0;	Will always be section, section will never repeat, but could meet in multiple locations, hence need for i 5 thru 12
	i = 1 or 5 or 9;	Will always be the day of week
	i = 2 or 6 or 10;  Will always be the period
	i = 3 or 7 or 11;  Will always be the building
	i = 4 or 8 or 12;  Will always be the room, when we find a building we need to check to see if it's in the sched_bldgs array, if not push it
