Null channel node

Used a place-holder and does not have a function of its own.

This chop is used a place-holder and does not have a function of its own. It is useful for tweaking data (using Edit Data Channels). It can also be used as the final OP in a chop network for exporting. If an unchanging OP like this is used to export, as your net changes you do not need to keep switching the Export flag. This also helps when fetching the result of a chop network from another network.
