#55 ECUT Task markers are not created

[Gerhard H. Leonhartsberger]

The ECUT task markers are not created when indexer is not selected on follow build configuration. This marker creation strategy should be changed. Instead of using a new marker type for ECUT marker types the C++ comments should be used for creating markers like this way:
// TODO: implement test case

This approach always works regardless if indexer follows build configuration or not.
