Generator improvements and cleanup
- generator now supports include-comments flag (as opt-in) - minor code cleanup in binapi-generator - remove obsolete unit tests - flatten examples from examples/cmd folder - introduce constant for checking compatibility in future versions Change-Id: I3545f2ba4b869a3b51d6d0de7e742f3f1e1be392 Signed-off-by: Ondrej Fabry <ofabry@cisco.com>
