18// AliTPCInverseCorrection class //
19// //
20// This is a wrapper that inverts an AliTPCCorrection. This is done by //
21// swapping the CalculateCorrection and CalculateInverseCorrection functions. //
22// The wrapped correction is supplied as a pointer and the class relies //
23// on the fact, that this pointer keeps pointing to the right object. //
24// However, the ownership is not changed, i.e. the wrapped correction //
25// will not be deleted when this correction is destructed. //
26// //
27// date: 27/04/2010 //
