vb_msrmnt_update_data

 Replace data and update file for MEG or EEG

 This function is used to create/update MEG-MAT or EEG-MAT file with arbitrary
 signal preprocessing function not supported by VBMEG. 

 [syntax]
   vb_msrmnt_update_data(inst_spec)

 [input]
   inst_spec : <<required>> <struct> instruction spec
       :  fields are as follows:
       :   .org_file     : <<required>> measurement file which will be updated
       :   .new_data     : <<required>> [n_channel x n_sample]
       :   .channel_type : <<optional>> depend on org_file
       :                 :  (org_file is MEG)
       :                 :    ['MEG'] | 'AXIAL' | 'PLANAR' | 'EXTRA'
       :                 :  (org_file is EEG)
       :                 :    ['EEG'] | 'EXTRA'
       :   .new_file : <<optional>> if you want to make new file.
       :                 :  ['org_file']
       :                 :  Empty means overwriting '.org_file'.
       :   .bin_data_dir : <<optional>> data stored directory.
       :                 : This parameter is valid only when 
       :                 : '.new_file' field is set.
       :                 : [(body of 'new_file')_bin]
       :                 : e.g. './new_0123.meg.mat' --> './new_0123_bin'

 [output]
   void

 [note]
   The size of inst_spec.new_data must be the same as the original one.
