// AliTPCCorrection class //
-// //
-// This class provides a general framework to deal with space point //
-// distortions. An correction class which inherits from here is for example //
-// AliTPCExBBShape or AliTPCExBTwist //
-// //
-// General functions are (for example): //
-// CorrectPoint(x,roc) where x is the vector of inital positions in //
-// cartesian coordinates and roc represents the Read Out chamber number //
-// according to the offline naming convention. The vector x is overwritten //
-// with the corrected coordinates. //
-// //
-// An alternative usage would be CorrectPoint(x,roc,dx), which leaves the //
-// vector x untouched, put returns the distortions via the vector dx //
-// //
-// The class allows "effective Omega Tau" corrections to be shifted to the //
-// single distortion classes. //
-// //
-// Note: This class is normally used via the class AliTPCComposedCorrection //
-// //
-// date: 27/04/2010 //
