add part count reduction to chef

• brings in controls to chef to support reducing the number of parts
• in current testing it fails at exit while freeing memory

@KennethEJansen

• I rebased on develop, blew away the change to convert (please submit another pr for that), and force pushed.
• https://github.com/SCOREC/core/pull/384/commits/34c9b5888c16e736ae16c1133b2825b804f43516 resolved the problem with failing existing tests - the global objects in the anonymous namespace were causing problems
• If you have a chance would you try running the part reduction test again?

[cwsmith]

there is a double free in the Output object created in the shrink group code here:

https://github.com/SCOREC/core/blob/a1ae6c1c31ae7d3582a1c01ce8074d873eec99bf/phasta/phCook.cc#L255

need to track this down with valgrind.

@KennethEJansen The leak is resolved and the new reduction ctest chef10 is passing. Would you mind sanity checking the result and if it looks good we can add the expected output to the test data dir and a diff against it in the test suite.

meeting notes

• the reduced output in paraview appears OK
• @KennethEJansen will test a larger case to do another sanity check
• @KennethEJansen will look at removing the coords.2 output file which is no longer needed

meeting notes

• removed the coords.2 output file and logic
• larger reduction test pending
