Code to change:
1) remove Forms from collection lists
2) To add the ability to add new dataElement Collections from the Pathways screen without going back to the main curation screens.
NB Currently a problem with the saving of new dataElementCollection in the pathwayAjaxFunctions.createCollection() calling the CollectionController.saveBasketCollection() method. From ajax the parameters do not appear in the params collection, whereas from the gsp they do...
MC-117 #close Updated the pathways nodes to add new data element collections, also fixed the filter so that Forms do not appear Data Element Collection listings.
Finish MC-117
