///////////////////////////////////////////////////////////////////////////
// Class AliSignal
// Handling of ALICE (extrapolated) signals.
//
// Note :
// ------
// Signal positions (r) and reference frames (f) are specified via
// SetPosition(r,f) under the following conventions :
//
// f="car" ==> r is Cartesian   (x,y,z)
// f="sph" ==> r is Spherical   (r,theta,phi)
// f="cyl" ==> r is Cylindrical (rho,phi,z)
//
// All angles are in radians.
//
// Example :
// ---------
//
// AliSignal s;
// Float_t pos[3]={-1,25,7};
// Float_t signal=120.8;
// s.SetPosition(pos,"car");
// s.SetSignal(signal);
// Float_t loc[3];
// s.GetPosition(loc,"sph");
// Float_t adc=s.GetSignal();
