A static radio-button column, corresponding to the checkbox column for multi-select, would be beneficial for single-select Grids in three ways:

1. Visually indicates to the user that rows are (single) selectable in a way that is consistent with multi-select.
2. Selection by clicking regular cells could be optionally disabled to prevent usability conflicts with interactive cell contents (e.g. buttons)
3. Solves current issue with editable cells not usable for seletion in vaadin-grid-pro by providing a dedicated selection element.
