/**
 * \brief Generic call to delete configuration settings.
 *
 * \warning This call should never be used by an outside program.  (i.e. A program that 
 *          links this library.)
 *
 * @param[in] deletefrom   The command that we want to use to delete a block.  As an example,
 *                         if we wanted to delete something from the <Managed_Networks> block,
 *                         this value would be set to "Delete_Managed_Network_Config".
 * @param[in] searchtag   The name of the XML tag that the supplicant will be using to identify
 *                        the block to be deleted.  Adding to the example above, we would need
 *                        to set this value to OU in order to match the proper configuration
 *                        data in the Managed_Network configuration structures.
 * @param[in] searchitem   The value that will be used with the searchtag to determine the 
 *                         exact configuration block that we should delete.  So, if we wanted
 *                         to delete a <Managed_Network> block with an <OU> of foo, we would
 *                         set this value to foo.
 *
 * @param[in] force   Should we force the deletion of the item.  (That is, delete it even if it is still
 *                    referenced somewhere else in the config.)  This parameter can take three different
 *                    values.  TRUE, FALSE, and -1.  The -1 means that this parameter isn't relevant to the
 *                    request, and should be left out.
 *
 * \retval REQUEST_SUCCESS on success
 * \retval REQUEST_TIMEOUT on timeout
 * \retval >299 on error
