ec5fb0ca3d Added a simple formatting class for Complex numbers. 
I had considered just implementing toString() on the complex
class, but I decided aginst it because some fields prefer
"j" to "i".  This ComplexFormat class is very straightforward,
will a number of TODOs, it is accompanied by a 10
tests.

04094833d5 Here's my idea for approximating derivatives. It follows the decorator layout of commons-collections. The main interface point is the UnivariateRealFunctionUtils type which is responisble for creating decorated UnivariateRealFunction objects. To demostrate the how the decorators could be used, I added the UnivariateRealFunctionUtilsTest class which computes a local maximum of a function using derivative decorators and the default solver.

4683ebbf93 I've thought about this and I like the idea of getting some of this code available in the cvs for experimentation, I'm going ahead and adding it for others to look at and consider. 
This directory will not get compiled into the regular build process or future distributions. We can work on an ant script to provide easy build of this if others think it neccessary.

005c054edd Rewrite StatUtils to use static instances of UnivariateStatistics. Benefits? 
1.) In the future, when we establish "Factories" for these objects, we'll be able to plug implementations in, even under our static Utilities classes for these functions. 

2.) The  user can always rely on the same result, whether using the StaticUtil, Univariate Container or direct UnivariateStatistic.
