It's either this or "ParseException" must be part of CM's interface, which
contradicts the new policy that all exceptions generated by CM should
inherit from the new "MathRuntimeException".

A checked exception will never be thrown because the method that throws it
(i.e. "parseOject(String)") is not used internally: "RealVectorFormat" only
uses "parseOject(String,ParsePosition)" which is not declared to throw a
"ParseException".
