Here is an updated LerpVectorMacro, which can be placed in the Macro folder, along with LerpMacro.
Also is the node program using the two macros, lerpVectorTest2 node.
2X "scale" bug still present.

The LerpVectorMacro contains 3 copies of the LerpMacro.

To save a macro, (for example LerpMacro), export LerpMacro from the canvas to a folder, naming it LerpMacro.nod.
Then copy the file LerpMacro.nod to the nodeeditor macros folder, for future re-use.
Similarly for LerpVectorMacro.nod, or any other Macro.
