// OnClickToggleAll function: toggles all checkboxes that are children of the CheckBoxList
// with ClientID = baseid. Recall that the children checkboxes will have an ID value equal to
// baseid_0, baseid_1, etc. The count parameter is the number of children checkboxes so the
// function knows how many checkboxes it has to toggle. Finally, flag is a string with the
// value 'true' or 'false' specifying whether the checkboxes need to be cleared (false) or
// set (true).
