Henner Zeller 3aa4484a3c Consistent use of 'override' for virtual methods in derived classes. 
o Not all derived methods were marked 'override', but it is a great
  feature of C++11 that we should make use of.
o While at it: touched header files got a -*- c++ -*- for emacs to
  provide support for that language.
o use YS_OVERRIDE for all override keywords (though we should probably
  use the plain keyword going forward now that C++11 is established)

Include module name for area summary stats 
The PR prints the name of the module when displaying the final area count.

Pros:
- Easier for the user to `grep` for area information about a specific module

Cons:
- Arguably more verbose, less "pretty" than author desires

Verification:
