Compare the outcome of the first group of tests with the first group in
			Grid_rendering.html.
		
		1a: GridFromHtml with single column with formatter for _item field
		
		1b: GridFromHtml with single column with get for order field, and blank label for 3rd column
		
		1c: GridFromHtml with single column with renderCell function
		(should look same as previous but with underlined first header cell
			and italicized first column values)
		
		
		2a: same as 1a, parsed from declarative markup (using a store)
		
		2b: same as 1b, parsed from declarative markup (using a store)
		
		2c: same as 1c, parsed from declarative markup (using a store)
		
		
		3a: Testing boolean property (un)specification in GridFromHtml
