* or hidden from all views).
*
* $options is an associative array from a mod_forumng_post::OPTION_xx constant.
* All available options are always set - if they were not set by
* the user, they will have been set to false before this call happens,
* so there is no need to use empty() or isset().
*
* Options are as follows. These are available in email mode:
*
* OPTION_TIME_ZONE (int) - Moodle time zone
* OPTION_VIEW_FULL_NAMES (bool) - If user is allowed to see full names
* OPTION_EMAIL (bool) - True if this is an email (false = standard view)
* OPTION_DIGEST (bool) - True if this is part of an email digest
* OPTION_COMMAND_REPLY (bool) - True if 'Reply' link should be displayed
* (available in email too)
*
* These options only apply in non-email usage:
*
* OPTION_SUMMARY (bool) - True if the entire post should not be displayed,
* only a short summary
* OPTION_NO_COMMANDS (bool) - True if this post is being printed on its own
* OPTION_COMMAND_EDIT (bool) - Display 'Edit' command
* OPTION_COMMAND_DELETE (bool) - Display 'Edit' command
* OPTION_COMMAND_SPLIT (bool) - Display 'Split' command
* OPTION_RATINGS_VIEW (bool) - True to display current ratings
* OPTION_RATINGS_EDIT (bool) - True to display ratings edit combo
* OPTION_LEAVE_DIV_OPEN (bool) - True to not close post div (means that
* child posts can be added within).
* OPTION_EXPANDED (bool) - True to show full post, otherwise abbreviate
* OPTION_DISCUSSION_SUBJECT (bool) - If true, and only IF post is a
* discussion root, includes subject (HTML, shortened as it would be for
* header display) as a hidden field.
*
* @param mod_forumng_post $post Post object
