/* MAPLINK.JS
   CIS_Web map link utilities.

   Version Information
    20011025a = Initial Release.
	20020528a = Removed database name array...when showing location, full database name must now be passed.
	20020709a = Added menubar=no code to map window open functions to align with debug versions.
	20021122a = Modified winLeft and winTop to support new winSize options.
	20021213a = Added drawmap function.
	20030102a = Added support for legend items in drawmap functions.
	20030108a = Fixed line info write in drawMap.
	20030304a = Added radial search data to showLocMap.
	20030305a = Modified search codes in showLocMap.
	20030403a = Completed fixSearchData function for CC map search form.
	20040715a = Added popup window test.
	20040730a = Added showAMap function, to use an absolute path to the map (also automatically shows full screen).
	            Use this function when you need a map link that will work in several contexts.
	20040831a = Added check for in=y in showAMap map string.
	20041006a = Added support for empty location list for drawMap.
	20041019a = Added support for icon=NONE in map draw requests.
	20041028a = Updated drawMap to send proper request when objArray is empty.
	20041130a = Added a check for the file extension to the sFile parameter on showLocMap.
	20041208a = Added a check for sFile when performing above check.
	20060426a = Modified all map launch functions to size map window without 1/20 of vertical space
	            to avoid task bar if isFrame = 3 (full size window).
