The not-consistent-with-equals natural ordering of BigDecimal get more explication too. While updating Object, I added some uses of apiNote and implSpec, as appropriate. While a signum method did not exist when Comparable was added, it has existed for many years so I removed obsolete text that defined a "sgn" function to compute signum.
