listGroups( )

Notes:

• For SECRET groups, only site admins, group admins, and group members can see a list of group and their content. However, if the suppressAuth option is set to true, all permissions are overwritten, and all site members (including non-group members) can see a list of groups and their content.
• This function's parameters are positional, and must be specified in the sequence shown in the syntax below. When specifying a parameter, use null as a placeholder for any unspecified parameters. For example, to specify limit only, call listGroups(paging, null). To specify supressAuth only, call listGroups(null, options).
