1) Removed entry for freemarker in visualization-beans-injection.xml

2) Commented out the part related to query.isSelectType() in all the QueryRunners
3) Added a generalized query for temporal vis that doesn't impose hierarchy. (Even if there are only people in a University/School, it works!)
4) Added print method to CoPIData
