Purpose

There are Dynamo basic samples containing nodes depending on Revit and as a result, the graph will run with warnings in other host and often times those nodes will not be resolved. I have removed the revit nodes in basic samples and move same samples into Revit folder.

Old Dynamo basic samples now become Revit samples.

New basic samples all run without warning in sandbox:
