How to use JavaScript to concat child records into a single field?

UPDATED NEW AND IMPROVED: I have updated this example with more generic code where all the parameters are floated to the top and a template is used to define how to summarize child records to the parent field in the report (and I am not through refactoring yet):

  //parameters:
  var dbid = "bkgzxdr4x";
  var dbidParents = "bkgzxdr6t";
  var dbidChilds = "bkgzxfptb";
  var apptoken = "q2aznmd9h7eymbwavpzjbsc8hcf";
  var n = 100;
  var relatedParentFid = "7";
  var relatedParentLabel = "related_parent";
  var clist = "3.7.10";
  var qbuClass = "QBU_Childs";
  var template = "<ul>{{#.}}<li>{{comment}}</li>{{/.}}</ul>";
