utils.decorate: Added @wraps to @arraysqueeze
utils.decorate: Added @wraps to @arraysqueeze

Discovered the functools.wraps decorator, to translate the docstring
  &c from the wrapped function to the wrapper. Still masks/munges the
  signature of the wrapped function, but much better than the completely
  blank docstring without @wraps.
