I tried the `compute_rt_moving_average.py` example with your new rebased branch and I get an error like this:

```sh
Traceback (most recent call last):
  File "/home/mainakjas/github/mne-python/examples/realtime/compute_rt_moving_average.py", line 43, in <module>
    reject=dict(grad=4000e-13, eog=150e-6))
  File "/home/mainakjas/.local/lib/python2.7/site-packages/mne/utils.py", line 327, in dec
    return function(*args, **kwargs)

    detrend=detrend, add_eeg_ref=add_eeg_ref, verbose=verbose)
TypeError: __init__() got an unexpected keyword argument 'proj'
```
any ideas?
