Description       : CSVdump Class defintion  
Language Version  : C++
OSs Tested        : Linux gcc3.0

The CSVdump class provides an interface to output TTM data
in CSV (comma seperated values) format.

The interface to the outside is provided by two methods:

  Open() - initaliaze output file
  Dump() - output one data record
	
Upon deletion output file is closed.
