Altered DropDown widget (#60)

* Altered DropDown widget: Added another mandatory path variable - selection value (depending on use case, one could prefer direct access to selection value rather than selection index); and another optional path variable - options (string variable to allow for dynamic change of options, as opposed to providing static list of options through arguments); and example with both static and dynamic dropdowns.

* Make second path variable optional, for backwards compatibility
