	// Parameters:	divContent: A reference to the div that contains the content to be 
	//				columnised. divContent will be displayed if javascript is not enabled. The text 
	//				content must be sub divided in p tags.
	//				divColumns: an array of divs to be populated as columns.
	//				lColCount: the number of columns to divide the content into
	//				sColClassName: CSS class to be applied to the columns
	//				sColId: Id to be used for column divs. Will be appended with the column number.
	//				bShowColumns: If true, the columnised content will be displayed initially, if
	//				if false, divContent will be displayed.
