/// \brief Macro to process survey and photogrammetry data of chamber 4
/// 
/// Macro loads the survey data from .txt file using AliSurveyObj.
/// Macro uses AliMUONSurvey... classes.
/// The transformations of the detection elements or chambers can be obtained 
/// in three ways:
/// - A: Fit of local to global transformation using the fixed button targets.
/// - B: Fit a plane to the sticker targets -> psi, theta
///      Use above psi and theta and fit remaining 4 parameters using the fixed 
///      button targets
/// -  C: Fit a plane to the sticker targets -> psi, theta
///      Use above psi and theta to calculate xc, yc, zc and phi by solving 
///      the equations from a local to global transformation of the fixed button 
///      targets
///
/// Methods A and B are prefered to C, and B is better if sticker targets are 
/// available and lie on a plane!
/// For slats only methods B and C can be used.
/// Various histograms are filled and printed for monitoring.
/// MisAlignment object is then created.
///
