Factorial method throws exception for zero 

           Summary: Factorial method throws exception for zero
           Product: Commons
           Version: 1.0 Alpha
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Math
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: frno@bredband.net


The MathUtils.factorial(final int n) method throws an IllegalArgumentException
for n=0 which is clearly incorrect since 0!=1 by definition.
