> IndexException and CardinalityException should be unchecked exceptions by analogy to
ArrayIndexOutOfBoundsException
> Having them be checked causes lots of try/catches in code that doesn't have a chance
of fixing the problem.  It should be understood that these can happen in any matrix manipulation
code just like IllegalArgumentException, ArithmeticException or ArrayIndexOutOfBoundsException
can happen in any numerical codes.
