-///////////////////////////////////////////////////////////////////////////
-// Class AliPosition
-// Handling of positions in various reference frames.
-//
-// This class is meant to serve as a base class for ALICE objects
-// that have a unique position in 3-dimensional space.
-//
-// Note :
-// ------
-// Positions (r) and reference frames (f) are specified via
-// SetPosition(Float_t* r,TString f) under the following conventions :
-//
-// f="car" ==> r in Cartesian coordinates   (x,y,z)
-// f="sph" ==> r in Spherical coordinates   (r,theta,phi)
-// f="cyl" ==> r in Cylindrical coordinates (rho,phi,z)
-//
-// All angles are in radians.
-//
-// Example :
-// ---------
-//
-// AliPosition q;
-// Float_t pos[3]={-1,25,7};
-// q.SetPosition(pos,"car");
-// Float_t loc[3];
-// q.GetPosition(loc,"sph");
-//
