   TPC Calibration Class for GOOFIE values. Drift velocity, gas composition and the gain. 

   The class AliTPCGoofieValues allows the access to GoofieValues. 

   The only constructor is loading data from ASCI file. 

   The methods make Tgraphs and TSplines of the time dependence of the values. 

   One method allows save the the graphs and spline togather with tree of allvalues into file.
