Updated comment to inform user to exclude .wid files when generating proj meta

in a string of failed widefield registration expids, the most tedious is usually to draw the reference points time and again. this upgrade adds two cases on the keypressfunction:
1) 'q' in addition to saving to adata, it exports the reference points to base workspace.
2) 'e' retrieves the base workspace reference points; use in the succeeding ExpID.
(after retrieval, the t-form needs to be calculated with the 't' key)

Added AData interface

bugfix - replaced size(list_of_mice,2) with length(list_of_mice) - georg

added hEEG_backup.m - georg

bugfix after recent changes

added days since observation to mouse list

implemented calc_widefield_act.m for 2ch data

Filtered meta_info passed to get_frame_times_widefield to correspond to current stackID, not entire expID.
- bug due to recent change in the way meta_info is loaded in load_exp. (new version loads it from adata, which contains meta_info for all the stacks of the current expID)

Fine tuned the 2ch roing in RoiQuest
