[Mne_analysis] filtering in MNE

[Matti Hamalainen]

Hi Elena,

The second set of filtering limits apply to EOG. mne_process_raw -- 
help tells you what the defaults are and how to change the EOG filter.

I am sorry that this feature was not mentioned in the manual. I have  
fixed the manual now but it is not in distribution yet.

- Matti
