Explain Grid splitter 
ans) 
Another attractive feature of Grid is its support for interactive resizing of rows and columns using a mouse or keyboard (or stylus or finger, depending on your hardware). This is accomplished with the GridSplitter class from the same namespace. You can add any number of GridSplitter children to a Grid and give them Grid.Row, Grid.Column, Grid.RowSpan, and/or Grid.ColumnSpan attached property values like any other children. Dragging a GridSplitter resizes at least one cell. Whether the other cells resize or simply move depends on whether they use proportional or nonproportional sizing
