[Clas12_software] clara update

[Vardan Gyurjyan]

Hi,
Based on our discussion at the software meeting today service engine based class (JServcie) has been modified.
As a result  both System.out and System.err print and println method calls in the JService inheriting class will be ignored by default (verbosity = 0 by default). Only after user calls the method setVerbosity(i), where i>0, System.out and System.err printouts will succeed.
