bml_raw2annot

 BML_RAW2ANNOT creates an annotation table from a raw

 raw - FT_DATATYPE_RAW

 returns an ANNOT table with variables
   'id' corresponds to the trial
   'starts' time represented by the trial
     'ends' time represented by the trial
   'duration' in seconds
   's1' double, first sample sync coord
   't1' double, time of first sample sample sync coord
   's2' double, second sample sync coord
   't2' double, time of second sample sample sync coord
   'Fs' double, sampling rate
   'nSamples' double, number of samples in raw
