/**
	This function takes the selected indexes of 2 radio button lists.
	It keeps track of previously selected indexes, so radioIndex1 or
	radioIndex2 can be updated by themselves or together.
	If both indexes are updated together, pass them both through (eg TotalPackageCost(2,1)),
	however if only one index is to be updated, pass through TotalPackageCost(2,-1) or
	TotalPackageCost(-1,1). 
	
	This method came into existance through needing to calculate a total cost from selections
	made to two different RadioButtonLists. It was designed to be used in conjunction with the 
	CustomRadioButtonList.cs class, to allow ListItems within a RadioButtonList to trigger javascript
	depending on which ListItem was clicked on.
	
	This method is also tightly linked to the javascript code written to the page from all the 
	Package Details pages.
	
	It looks for an array called 'costArray'. The structure of the costArray is as follows:
		costArray = { [innerCostArray]*, [innerCostArray] }
		
		innerCostArray = {travellers, index1, index2, cost}
			where:
				travellers	=	If the package cost can easily be determined by (number of travellers * cost), this is set to -1
								If the package cost is not determined by this way, this value is set to the number of travellers that matches the cost below
				index1		=	The required selected index of the first RadioButtonList
				index2		=	The required selected index of the second RadioButtonList (if there is only one RadioButtonList this is set to -2)
				cost		=	The totalCost when the above indexes have been selected (multipled by the number of travellers if the above travellers variable is not -1)
