ssi91 79407c87fb remove extra definition of printIndented
add CommonBaseTestCase class and inherit some of TestCase classes from it. Since that, remove print source extra definitions

create the base defifnition for printUpdatedExpectations and remove extra definitions of the method

make CommonBaseTestCase c-tor explicit

include AnsiColorized.h and sort includes

implement a common result checker

move the common implementations into TastCase
