configuration option called --enable-global-partition. The old option is still
available, but not printed with --help. Also added the autotest script
basictest.sh to make it easier to write machine tests.
Added an example code to test CG on a 4D HYPRE_SSTRUCT complex problem.
Added regression tests for bigint, maxdim, and complex.
Added a test to make sure double types are not added to the source.
