Tim O'Brien 6c07bd13a8 Addressed exception "swallowing" in test coverage. From Phil's recent 
email: "If the test case throws an unexpected exception, the test 
should fail.  ....[fix] these by changing the test method signature to 
throws Exception.  This also eliminates the need to import 
MathException everywhere."

Tim O'Brien e0452e4d79 Pre Issue 29012, getKurtosisClass() did not have a tolerance; therefore, 
any non-zero kurtosis was consistently mesokurtic.  Instead of getting 
into this level of detail, getKurtosisClass() has been removed, it is a
subjective measure not appropriate for DescStat.

Tim O'Brien 9459e748c8 ComplexFormat now handles situations where either the real or 
imaginary part is NaN, POSITIVE_INFINITY, or NEGATIVE_INFINITY.
Three new tests were added to address these situations.
