getObjectiveString

 getObjectiveString
   Returns a string representing the objective function (e.g. 'MAX Growth
   - 0.5 HXT4').

   max                 true if the objective function should be maximized
   objectiveNames      cell array of reaction names
   objectiveValues     the corresponding coefficients for each reaction

   objectiveString     the calculated objective function

 Usage: objectiveString = getObjectiveString(max, objectiveNames,
           objectiveValues)
