ENH: Added ctest test options PROCESSORS and RUN_SERIAL. These allow specification of resource allocation for given tests running with the ctest -j N option. RUN_SERIAL ensures that a given test does not run in parallel with any other test. Also forced appending of "..." to the longest test name in ctest.
