// This class generates misalignment for PMD. In particular it defines
// the misalignment in the three canonical scenarios: "ideal", "residual"
// and "full".
// It is meant to be run standalone or from the steering macro
// $ALICE_ROOT/macros/MakeAlignmentObjs.C
// looping on the detectors.
//
// Macro to randomly displace the 4 sectors of the PMD
// in each plane. Each sector (to be misaligned) 
// of PMD houses the following :
// (a) 6 modules of preshower plane
// (b) 6 modules of veto plane
// (c) The FEE boards on back plane of each module
// (d) 6 modules of convertor plates
// The clustering is done module-wise
// The actual amount displacement will be provided
// by the survey data and has to be converted into
// displacement in x,y,z,theta, phi and psi 


// Now specify the path of the module to be misaligned
// as followed in the PMD geant
