* Bug: In CRL::MeasureSet::toStringHeaders(), check and issue a warning
if a measure label ends with a "." (dot).
* Change: In CRL::ToolEngine::getMeasure(), return the data measure
by pointer instead of by reference (easier to manipulate afterwards).
* New: In EtesianEngine::place(), add the placement runtime (under label
"placeT") to the measure set.
* New: In KatanaEngine::dumpMeasures(), add the Etesian runtime to the
set of measures.
