Moved data definition classes to DetaFormats/... directories (#808)
* Moved data definition classes to DetaFormats/... directories To avoid circular dependencies moved some classes from O2/Detectors/Base to O2/DetaFormats/... Also some math utilities were moved to O2/Common/MathUtils as well as constants moved to O2/Common/Constants The massive change of multiple files is mostly due to the fixes of headers and namespaces * Set of fixes and methods needed for ITS-TPC matching Static method to init Bfield from propagator, MagFieldFact ownership fix: Bug fix: MagFieldFact factory class cannot own the field it created: since the FairRunAna and TGeoGlobalMagField delete the field created by the factor, we have to use naked new in the factory, which cannot own the field Apply material correction in backpropagation fit (CookedTracker) Bug fix: CookedTrack::getChi2 should return float (CookedTrack) Use double for all error matrix calc. + fix in array init + extra getters (Track) Add comparison methods to MCCompLabel Fix: add ClassDefNV for TrackTPC + make getter const Added method to load geometry from file (GeometryManager) Separate methods for field and geom inits (initSimGeomAndField.C)
