Ygdrasil - mover

mover derived from ygTransform

Description: a quaternian based motion path between two positions and orientations

notes:

derived nodes inherit all messages from their base classes
see reset method for default settings
the set/value/position message takes a value between 0 and 1
values outside of the 0 to 1 range will be interpolated accordingly
