/**
 * Description:     Deletes the entire database by removing internal SQLite DB file
 *
        /*from   ww  w  .j  a v a  2s .  c o m*/
 *
 * Dependencies:    Used in AIMSICD.java
 *
 * Notes:           See Android developer info: http://tinyurl.com/psz8vmt
 *
 *              WARNING!
 *              This deletes the entire database, thus any subsequent DB access will FC app.
 *              Therefore we need to either restart app or run AIMSICDDbAdapter, to rebuild DB.
 *              See: #581
 *
 *              In addition, since SQLite is kept in memory during lifetime of App, and
 *              is using Journaling, we have to restart app in order to clear old data
 *              already in memory.
