/*
To enable a survey, you must first set up a survey on SurveyMonkey and obtain the survey url.

On the page where you want the survey to appear:

1) Add this script library: <script src="/includes/surveys/surveymonkey.js"></script>
2) Define variables in a script block for smurl and survey
3) Call popupSurvey: popupSurvey("/includes/surveys/smsurvey.asp","tpsurvey",smurl,survey);
4) Create an inline scriptblock and call showSurveyLink: showSurveyLink(smurl,survey);
