+      - Removed call to TGaxis::Optimize for compilation under root 
+        versions > 3.03, since in them this procedure is no longer existing.
+	I did this to allow compilation under root_3.04, since earlier 
+	versions has a bug which prevents from plotting in the simple way
+	some variables in a tree (example: fConc and others in the output 
+        of star.C). This is a temporal fix, I guess something will have to
+	substitute the call to Optimize...
