Review comment:
       As BillingUtilils.getHeader() returns the report header as a string,it 
should be split by the CSVFormatter.SEPARATOR to retrieve the length of the 
header.
   As CSVFormatted is used in BillingUtils class, I decided to encapsulate the 
the split procedure
   in the getTotal method
