[Added]: * findUnusedQuestions script: a script that compares the "clean up" information gathered from the HtmlFormQuestionnaire with the available Question Instances of the individual services. [Changed]: * HtmlFormQuestionnaire: provided some simple support functions for "clean up". So far these are only "get" but don't change anything. * TermCountToGoogleChart: allows for more than a two column data structure and improved sorting. Also some code restructure.
