This is a stupd commit that tries to get rid of SonarQube complaining about duplicate lines.

…cttsmap and cstsmapmerge to the new logging conventions

… cases, restructured csiactobs to avoid code duplication and added csobsdef::obs() function to retrieve observation container

The new GApplication logger support function take the chattiness level as the first argument.

The building of a cuve on the fly raised issue with memory going out of scope. This is fixed by making the CTA event cube a member of ctbin, and having the cube() method returning a reference to that member
