> Headers and cells can now be selected however there is some inconsistency to their behaviour.
> It is possible to select a header cell first and then a body cell with {{ctrl}} pressed and both remain selected. If however you select first a body cell and then a header cell with {{ctrl}} pressed the body cell becomes deselected (this is because {{HeaderSingleCellSelectionStrategy}} clears the models selections).
> Also, following changes for "drill down" {{LiteralExpressionGrid}} and {{UndefinedExpressionGrid}} "act on their own" regarding selection. i.e. create a {{Context}} and add a new {{ContextEntry}} setting its {{Expression}} to a {{LiteralExpression}}. Select multiple cells with {{ctrl}} and when the {{LiteralExpressionGrid}} and {{UndefindExpressionGrid}} cells' are selected the {{Context}} cells become deselected. Ideally the parent cell selections should change too so they _appear_ to be visually selected together.
