/**
 * Comments for any content
 *
 * Related classes:
 * - BxDolCmtsQuery - comments database queries
 * - BxBaseCmts - comments base representation
 * - BxTemplCmts - custom template representation
 *
 * AJAX comments for any content.
 * Self moderated - users rate all comments, and if comment is
 * below viewing treshold it is hidden by default.
 *
 * To add comments section to your module you need to add a record to 'sys_objects_cmts' table:
 *
 * - ID - autoincremented id for internal usage
 * - ObjectName - your unique module name, with vendor prefix, lowercase and spaces are underscored
 * - TableCmts - table name where comments are stored
 * - Html - 0 - convert new lines to <br /> on saving, 1 - standard(default) visual editor, 2 - full visual editor, 3 - mini visual editor.
 * - PerView - number of comments on a page
 * - IsRatable - 0 or 1 allow to rate comments or not
 * - ViewingThreshold - comment viewing treshost, if comment is below this number it is hidden by default
 * - IsOn - is this comment object enabled
 * - RootStylePrefix - toot comments style prefix, if you need root comments look different\
 * - ObjectVote - Vote object name to process comments' votes. May be empty if Comment Vote is not needed.
 * - TriggerTable - table to be updated upon each comment
 * - TriggerFieldId - TriggerTable table field with unique record id of
 * - TriggerFieldComments - TriggerTable table field with comments count, it will be updated automatically upon eaech comment
 * - ClassName - your custom class name if you need to override default class, this class must have the same constructor arguments
 * - ClassFile - file where your ClassName is stored.
 *
 * You can refer to BoonEx modules for sample record in this table.
 *
 *
 *
 * @section example Example of usage:
 * After filling in the table you can show comments section in any place, using the following code:
 *
 * @code
 * $o = new BxTemplCmts('value of ObjectName field', $iYourEntryId);
 * if ($o->isEnabled())
 *     echo $o->getCommentsBlock ();
 * @endcode
 *
 * Please note that you never need to use BxDolCmts class directly, use BxTemplCmts instead.
 * Also if you override comments class with your own then make it child of BxTemplCmts class.
 *
 *
 *
 * @section acl Memberships/ACL:
 * - comments post
 * - comments edit own
 * - comments remove own
 * - comments edit all
 *
 *
 *
 * @section alerts Alerts:
 * Alerts type/unit - every module has own type/unit, it equals to ObjectName.
 *
 * The following alerts are rised
 *
 * - commentPost - comment was posted
 *      - $iObjectId - entry id
 *      - $iSenderId - author of comment
 *      - $aExtra['comment_id'] - just added comment id
 *
 * - commentRemoved - comments was removed
 *      - $iObjectId - entry id
 *      - $iSenderId - comment deleter id
 *      - $aExtra['comment_id'] - removed comment id
 *
 * - commentUpdated - comments was updated
 *      - $iObjectId - entry id
 *      - $iSenderId - comment deleter id
 *      - $aExtra['comment_id'] - updated comment id
 *
 * - commentRated - comments was rated
 *      - $iObjectId - entry id
 *      - $iSenderId - comment rater id
 *      - $aExtra['comment_id'] - rated comment id
 *      - $aExtra['rate'] - comment rate 1 or -1
