 * This class implements a certificate store which is stored on a file on the
 * device.  NewL calls the constructor and ConstructL. The constructor does
 * nothing except initializing to 0. ConstructL calls OpenStoreL, then RestoreL
 * and then sets the values of iStoreInfo.  OpenStoreL opens the store and
 * copies it from the ROM if necessary.  RestoreL()
