Add NCSortInOrder and add NCFilterOutLongPolys to NCGBX

[jared-hughes]

Sometimes NCMakeGB would produce a huge Gröbner basis, so NCProcess printed out too many polynomials to look at easily. We (Bill+I) found it helpful to cache the output of NCMakeGB, filter that down (using NCFilterOutLongPolys introduced in this PR), then output that without re-computing the Gröbner basis (using NCSortInOrder).

The output of NCSortInOrder is the same as NCProcess, except NCSortInOrder does not call the NCMakeGB first.

Implementation note -- the options are specified separately, so a SetOptions[NCSortInOrder, {printReport -> False}] would not affect the behavior of NCProcess, and vice versa.

Note I ran make usage to convert the documentation changes to the .usage file. Not sure if there's anything else in the makefile that should be ran.
