GOFMM's adaptive level restriction may not be working correctly

[ChenhanYu]

Adaptive level restriction requires inspection or fix.

Now by default, secure_accuracy (level restriction) is on. I will carry out the new command line parser.

Notice that when the leaf is not skeletonized, securing the accuracy will change the near interaction list. That is all leaf nodes that cannot be skeletonized must be also be added to all other's near interaction lists. To avoid this problem, when secure accuracy is turned "on" we will force the leaf node size to be not larger than the maximum rank.

secure_accuracy now works correctly on both shared and distributed GOFMM. You can set this option in CommandLineHelper. This option will be propagated to the other scripts in the following update.
#36 shares the same problem.
