load channel list
[usage]
ch_list = vb_msrmnt_get_channel_list(msrmnt_file, active_swt)
[input]
msrmnt_file : <required> measurement file which includes channel list
: e.g. EEG-MAT (.eeg.mat) MEG-MAT (.meg.mat)
active_swt : <optional> <<boolean>> [false] switch for active channel
: true) return only active channels (EEG)
: false) return all the channels (EEG)
[output]
ch_list : (cell array) list of channel label [N x 1]
[note]
acceptable "Measurement" are :
'MEG', 'EEG'
