100% code coverage

[turdusmerula]

When there is a need of 100% code coverage over tests there is always cases where this target can be met ...
For example we have a mandatory quality rule to always have a default case on a switch block but when default case is unreachable we can't have the 100% target.
Second example in defensive code a catch block whose exception can not be fired by unit test makes the code under the wanted 100%.

It would be interesting to have a way to filter known unreachable code from the analysis or from the report with a special comment block for example.
