[Eeglablist] clean_asr

Dear Srinivas,

I don't know how many channels you have, but this seems too short.

resting EEG as calibration. The reason could be artifacts in resting EEG.

I'm not sure if it makes sense to learn from resting data and use it to
interpolate data during walking... but it may be a trivial issue. I can't
tell for sure.

Record data as long as possible so that even after severe cleaning decent
amount of data remains. Don't forget the saying GIGO (garbage in, garbage
out).

I need only 300 msec to answer 'yes'
