Code cleanup: "ISAACRandom"
---------------------------

                 Key: MATH-734
                 URL: https://issues.apache.org/jira/browse/MATH-734
             Project: Commons Math
          Issue Type: Improvement
            Reporter: Gilles
            Assignee: Gilles
            Priority: Minor
             Fix For: 3.0


In revision 1232899, I started to clean up the code (mainly, removing the 
one-letter instance variables, that can easily be confused with local ones 
within methods, making the code harder to understand and maintain).

Other points I'd want to handle:
* Should "Serializable" be implemented for such classes? I think not; 
especially if it supposed to be used for "secure" applications.
* (Related to the above) I'd remove the "transient" keyword.
* The contents of method "allocArrays" should be moved to within the 
constructor.
* It is not recommended to call non-final "public" methods ("setSeed") from 
within the constructor, because an overriding code could access a not fully 
uninitialized object.
* All initialization should take place within a single, most general, 
constructor and the other constructors should call that one (using the 
{{this(...)}} statement).
