CoordinateInterpolator linearly interpolates among a list of 3-tuple MFVec3f arrays, producing a single MFVec3f array that is fractional average between two nearest arrays in the list. Authors can ROUTE value_changed output events (an array of 3-tuple SFVec3f values) to a Coordinate node's point field, or to another MFVec3f field.
