/* ********************************************************************
    
    NOTE: This script is designed to be included before any other script,
    due to the fact it handles browser and document.all issues! dw 8/7/01
	
	This is the Utility.js client side page, which contains commonly 
	used JavaScript functions required by the RQQ Replacement web site
	It consists of the following functions:
	1)	browserSniffer
			This code should be run as soon as the Utility.js page is loaded.  
			It detects what browser configuration is being used.
	2)	searchorama()
			This function is passed a search string, and will search all the 
			producers in the Producer List box.  If a match is found, the first
			line which matches will be selected.  If a match is not found,
			the user will be alerted with a message to that effect.
	3)  getProducer(strAction)
			Identify the subproducer/producer selected for identity change
			Submit if a subproducer
	4)	submitProducer() 
			This routine is invoked on double-click of the Producer Select tag.  
			The requested producer will be returned to DBA.
	5)  openSizedWindow()
			This routines opens a new window of a specified size and focuses 
			on it.
			rg - adapted from fmc function on QuoteList.asp
	6)	getObjById(objectID,withStyle)
			This function retrieves an object reference for a page element
			or style, referenced correctly for each browser version.  
			It requires the string variable for browser version, automatically 
			defined below, which is returned by browserSniffer();
	7)	writeToDiv(divId, strMessage, strMessageClass)
			This function writes a message to a specified <DIV> HTML element.
	8)	useStandardStylesheet()
			This function writes a stylesheet link based on the browser in use.
			This is necessary to adjust for the differences in CSS support.
	9)  fakeDisableCheckbox(obj)
			simulates disabled checkbox in ns4
	10)	fakeDisableRadio(oRadio)
			simulates disabled radio in ns4
	11)	2 lines of executable code to establish the browser variable and 
			the docAll variable for the page.
	12)	changeVisibility(objname,visibility,...)
			change the visibility of the given object in the arguments.
