Added some new features:
Harmony Color Node
New: Auto Sahder Generator Node to add materials for up to 4 objects using the input color sockets (i.e. from the Harmony Color outputs)
Improved the output of values and updates by using own sockets for input and output
Improved 3D View Node
some minor bug fixes and improvements
First release, also available on Github. Please keep in mind, this is for developers to have an easy way of adding node editors and how to fill them with own nodes. This is not intended for production use, use it on your own risk. Always make a backup of your Blender file to avoid loosing data if anything crashes.
