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.

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.
