     getTooltips returns the names of the tooltips for the active MVC. 
     These will be the tooltips when the mouse over event is set to
     show tooltips. Currently, the tooltips can be set to be either the
     row names or the values from one of the data frame's columns.  The
     default is to use the row names as tooltips.  Until the tooltips
     have been set using the function, setTooltips, this function will
     return NULL.
