DataGrid SetMask Method

Sets the RowsMask and ColumnMask property.

   R←I SetMask R C

I is a DataGrid instance. R is a Boolean vector the same length as the number of rows in I, marking rows to be dislayed.

C is either a Boolean vector, or a list of column names. If a Boolean, it must be the same length as the number of columns in I, marking columns to be dislayed. If a list of column names, it indicates the columns to be displayed and their order.

R is 0

This method should be used after the application is up and running and the DataGrid has been initialized.
