** \brief Date Delegate
**
** The date delegate handles the WDateTime value from the model.  Even though a 'transaction'
**  is posted on a 'date' and not particularly a time, the gnucash system still is sensitive
**  to time values in date-only fields.  In the case of the transactions, the 'time'
**  component is set to 10:59:00.  There is a macro that contains this value
**  'GCW_DATE_DEFAULT_TIME' which should be used to reference the correct time-value.  The
**  time-component is important since when reading items out of the database, gnucash
**  responds poorly to posted dates that have a 00:00:00 time component set, it must be set
**  to the 10:59:00 value.  This delegate makes sure that happens (probably shouldn't be
**  done here).

    ** \brief Edit State
    **
    ** A thing about editState, setEditState, setModelData.  Each of these use 'cpp17::any' data
    **  for handling data.  When you 'editState' you can return anything you want that will also
    **  be digested by 'setEditState'.  Then, also, therefore, setModelData will also receive
    **  anything from 'editState'.  So, this can be a handy tool for passing around different
    **  editor info that is specifically tied to a row or item that is being edited.  Right now
    **  we just return the date value, since that's what we're using and poking straight in to the
    **  model and what not, but we could be passing around any object/date/type... just sayin.
