• Made layout and row selector private classes.
• Improved structure parsing code.
• Added a property on VirtualGrid? to add the row selector without adding it to the structure explicitly.

• Forgot to replace dojox.grid._grid.GridRowView? with dojox.grid._RowSelector in the tests.

One other suggestion that may go along with this - it would be nice to be able to specify a "relative" width of a grid - or to say that widths are relative...so, for example, if you have 3 columns, with relwidth of 1, 2, and 3, then the second column would be twice as wide as the first, and the third would be 3 times as wide as the first...but the sum total of all columns will fill the available width of the grid.

It could also be the default if no units are specified on the width...just some thoughts.

I have a mixin that we are using to accomplish this. It's not ready to be submitted as a patch or anything - but if you like, IM me and we can discuss a bit more.
