read_oxy

 LOAD_OXY - Load a *.oxy file from the AOML Winkler titration system. 

 USAGE:
  oxy = load_oxy(filename);

 INPUT:
     in_file: string containing path and name of input file

 OUTPUT:
   oxy: struct with fields
     date: time and data of titration (usually wrong on AOML computer)
     station: string indicating station/cast
     depth: depth field in the titration computer, frequently Niskin bottle Rosette position
     sample_bottle: label of the sample bottle in which the titration was done.
     thio_vol: solume of Thiosulphate in the titration.
     oxygen: oxygen in units of micromoles per liter.  See ox_units for conversion to other
       more standard units for analysis. 
     units: 'mmmperl'
