Used to produce a group box with specific layout parameters, such as a series of radio buttons, in which two or more properties are located.

If you respecify a group, the expectation is that you will be adding properties to it.

If you want to remove properties from a group then you have to create a new group, by adding a trailing space to the name for instance.

System Architect will attempt to present all properties within a group in the same page of the dialog.
