ConnectCore Cloud Services examples are included in 'dey-examples' repository
so they can be built from here and also imported in Eclipse/Digi Application
Development Environment for Linux with the samples wizard.
The example 'upload_file' has been removed since currently there is no support
for binary data points in the CCCS daemon/client model.
