delete autosaved cycles of not saved trees from file.
Added TNamed Object to tree that indicates the tree type, if it is a GoAT or a Physics tree. An Acqu tree does not have a TNamed flag. Also added functions to GTreeManager to Set the type of output file (SetAsGoATFile() and SetAsPhysicsFile()), and to check the input file (IsAcquFile(), IsGoATFile() and IsPhysicsFile()). GoAT class and example Physics classes will check the input type and set the correct output type.
