Issue #154 First version. Untested, but compiles. Also still need to handle the simulator case, which parses enabled_wuclasses.xml at startup instead of running the generated code.
Issue #154 Multiple sensors works for real nodes. enabled_wuclasses.xml in wunode config is set for entrance floor of the dollhouse. Simulator is broken now, so can't merge this back to develop just yet.
Issue #154 Work in progress on adapting the simulator to the new enabled_wuclasses.xml. Can create multiple instances, but can't set properties yet.
Issue #154 Modified enabled_wuclasses.xml for other configs
Issue #154 Renamed pin enum to be platform independent.
Merge branch 'multiple-sensors-per-node' into tmpmerge
