* Check flag before rebuilding summary address nodes
* Performance: Use vector instead of set and map locally in thread
* Performance: Skip looking for restart summary filenames for opm-common
* Move adding of case realization parameters to OpenMP loop
* Add unit test for file path operations
* Performance: Avoid using cdUp() function when splitting path into strings
