Multi-selection fails with initial selection

[Mikael Andersen]

Hi at pqgrid,

We experienced a problem with initial selection being set and the use of "Shift+click" to do multi-cell selection.
Its reproducable in demo following these steps,

* Open demo: https://paramquery.com/pro/demos/grid_parts
* Insert this line after creating grid, f.x. on line 102: grid.setSelection({ rowIndx: 0, colIndx: 0})
* Run (top, leftmost cell is selected as expected)
* Hold shift and click on a different cell to do a block selection

Nothing happens and this error is displayed in console:
Uncaught TypeError: can't access property "r1", n is undefined

Please use grid.Range() API instead of setSelection.

Code: [Select]

        grid.Range({
            r1: 0,
            c1: 0,
            firstR:0,
            firstC:0
        }).select();
