import_entire_log

 import_entire_log() - import log information about events listed in blf file 
              
 Usage:
  >> log_info=import_log(asciilogfile,blf_evnum)

 Inputs:
   asciilogfile = name of ascii version of Kutaslab .log file (a
                  string).  This can be generated by log2asci or logcat2.  If
                  generated by log2asci the sampling rate must have been
                  specified so that event times columns are in ascii file.

 Outputs:
   log_info = a matrix of log information. Each row corresponds to
              an event.  The columns are:
              1) Item Number
              2) Event Number (stim/resp code)
              3) Condition Code
              4) Flag
              5) Time of Occurrence (in sec)
