/** @addtogroup Account_Quickfill Quickfill Account Names
    For systems with a large number of accounts (>500), the creation 
    of the account name quickfill can take a significant amount of 
    time (tens of seconds in bad cases).  This routine will build 
    a cache of account names that can be shared by all registers, 
    thus dramatically improving the performance of opening a new 
    register.

/** Create/fetch a quickfill of account names.  
 *
 *  The quickfill is created out of all of the subaccounts 
 *  the the account group, filtered by the 'skip_cb' callback.
 *  If 'skip_cb' is not NULL, and if it returns TRUE when passed
 *  a particular account, then that account won't be included in
 *  the quickfill.  The 'cb_data' is passed to the callback.
 *
 *  The quickfill is created only once; it is then stored with
 *  the QofBook that is the parent of the AccountGroup.  It is
 *  automatically destroyed when the QofBook is destroyed.
 *
 *  Multiple, distinct quickfills, for different uses, are allowed. 
 *  Each is identified with the 'key'.  Be sure to use distinct, 
 *  unique keys that don't conflict with other users of QofBook.
 *
 *  This code listens to account creation events, and automatically
 *  adds new accounts to the quickfill list (assuming skip_cb allows
 *  it).  This code does not currently listen to account-destroy
 *  events.
