Use functools for codeTiming decorator.

[mgjarrett]

What is the change?

Use the @functools.wraps() decorator to transfer attributes from the wrapped function to the wrapper function created by @codeTiming.timed.

Why is the change being made?

The codeTiming.timed decorator was interfering with the API docs. See interactBOL and interactBOC under the LatticePhysicsInterface, where the docstrings did not make it into the docs.

This update will get the docstrings to render correctly in the API docs:
