Summary
Function: llTargetOffsetOmega( vector axis, float spinrate, float gain, vector offset );
Rotates the object around axis passing through offset at spinrate * llVecMag(axis) in radians per second with strength gain.

Specification
Physics
- If the object is not physical then the effect is entirely client side.
- If the object is physical then the physical representation is updated regularly.
Link Sets
TODO: Not really sure about this - I suppose that the offset could be relative to various coordinate systems.
- If the script is attached to the root prim, the entire object rotates around the region axis
- If the object is attached then it rotates around the attachment axis
- If the script is attached to a child prim, the prim rotates around the local axis
- A Child prim can rotate around its own axis while the entire object rotates around another axis.
Caveats
- If the object is not physical then the rotation is only a client side effect and avatars and objects may move around the object as if it were not rotating at all.

Examples
<lsl>//rotates the x axis once per second,
// rotates the y axis 3 times per second,
// rotates the z axis once every two seconds.
// combined the rate is about 3.20156 revolutions per second

Notes
Use llVecNorm on axis so that spinrate actually represents the rate of rotation.
