-// ----------------------------
-// Class for misalignment of geometry transformations

-//This performs the misalignment on an existing muon arm geometry
-// based on the standard definition of the detector elements in
-// $ALICE_ROOT/MUON/data
-//
-// --> User has to specify the magnitude of the alignments, in the Cartesian
-// co-ordiantes (which are used to apply translation misalignments) and in the
-// spherical co-ordinates (which are used to apply angular displacements)
-// --> If the constructor is used with no arguments, user has to set
-// misalignment ranges by hand using the methods :
-// SetApplyMisAlig, SetMaxCartMisAlig, SetMaxAngMisAlig, SetXYAngMisAligFactor
-// (last method takes account of the fact that the misalingment is greatest in
-// the XY plane, since the detection elements are fixed to a support structure
-// in this plane. Misalignments in the XZ and YZ plane will be very small
-// compared to those in the XY plane, which are small already - of the order
-// of microns)
-
-// Note : If the detection elements are allowed to be misaligned in all
-// directions, this has consequences for the alignment algorithm
-// (AliMUONAlignment), which needs to know the number of free parameters.
-// Eric only allowed 3 : x,y,theta_xy, but in principle z and the other
-// two angles are alignable as well.
