UniGUI should have UniGridPanel,
UniGridPanel is a kind of Panel,
the Panel have rowCount and colCount property,
if I set rowCount=5 and colCount=3,
than the UniGridPanel will have rows=5 and cols=3,
there will be 5*3 cells,
all the cells are the same width and same height,
in any Cell,I can place a UniImage\UniBitBtn etc...
Of course,just like UniHiddenPanel,
In the design time,all the cells have borders,
But in the runtime,alll the cells have no borders.
