Python Learning in Blender- Sine expression to Drive Bone Rotation

A quick python learning exercise in blender:

1. Scripted various controls with arguments for names/limits/shape etc
2. Scripted a bone chain definition with arguments for names/numberOfBones/transformPlacement/axis/O.O.R etc
3. Created a script to iterated through the bones and deliver a sine expression using the controllers Y transform as input variables for the bones XYZ rotations - sin(frame*"freq+...etc")

•  Driver delivery: https://blender.stackexchange.com/questions/13747/pose-bone-drivers-through- 

Now - the expression needs a little work (ie: clamp(#,#,#) etc), before I can expand upon it.
