Details: - Added new lines of input to the test suite's input.operations file, which allows the user to disable entire sections (levels) of tests. Before this change, the user had to manually disable each operation tests's "master switch". (This is why input.operations.0 existed: to allow a more convenient starting point for someone who only wanted to test one or a few operations.)
