This class implements the UI functionality of the topics scroller control.
 
During development, there has been a few changes which were not *fully* done
mainly in converting the topics and time boxes
from combobox and time box to normal textboxes,
so in the code they might be referenced as combobox or timebox. This should be
rather understood as topicstextbox and timetextbox. 
Important behaviour of this control is that there is always a
blank row at the end, in which the user can enter data. 
Once the row is not blank (thus, the user entered data...),
a new blank row is added. 
Once the user removes the last *unempty* row, binsertRowy deleting its data, it becomes
the *last empty row* and the one after is being automatically removed. 
The control shows 5 rows at a time. 
If, for example, only 2 rows exist (from which the 2ed one is empty...)
then the other three rows, which do not exist in the data model, are disabled.
 
The following other functionality is implemented:
 
0. synchronizing data between controls, data model and live preview.
1. Tab scrolling. 
2. Keyboard scrolling. 
3. Removing rows and adding new rows. 
4. Moving rows up and down. 
 
This control relays on the ControlScroller control which uses the following
Data model: 
1. It uses a vector, whose members are arrays of PropertyValue. 
2. Each array represents a row. 
(Note: the Name and Value members of the PropertyValue object are being used)
3. Each property Value represents a value
for a single control with the following rules: 
3. a. the Value of the property is used for as value
of the controls (usually text). 
3. b. the Name of the property is used to map values
to UI controls in the following manner: 
3. b. 1. only the Name of the first X Rows is regarded,
where X is the number of visible rows (in the ainsertRowgenda wizard this would be 5,
since 5 topic rows are visible on the dialog). 
3. b. 2. The Names of the first X (or 5...) rows are the names
of the UI Controls to hold values. When the control scroller scrolls,
it looks at the first 5 rows and uses the names specified there to map the
current values to the specified controls. 
This data model makes the following limitations on the implementation:
When moving rows, only the values should be moved. The Rows objects,
which contain also the Names of the controls should not be switched. 
also when deleting or inserting rows, attention should be paid that no rows
should be removed or inserted. Instead, only the Values should rotate. 
To save the topics in the registry a ConfigSet of objects of type CGTopic is
being used.
This one is not synchronized "live", since it is unnecessary... instead, it is
synchronized on call, before the settings should be saved.
