[math] implementation of Polynomial Function

Attached are two new files that implement a Polynomial as a 
UnivariateRealFunction and should be added to the 
org.apache.commons.math.analysis packages in both java and test 
respectively.

 I do not have commit privileges and would appreciate on the the math 
contributors or members to add these.

   also, I have added a patch that will remove the firstDerivative and 
secondDerivative methods from the UnivariateRealFunction interface (and 
appropriate unit test).  This item was still pending consensus.  I plan to 
write a couple classes such as UnivariateRealDifferentiator that will give 
numeric approximates using point evaluation to achieve this.  I also plan 
to contribute UnivariateRealIntegrator pattern.

Thanks Matt,

I'll apply and test both this and the earlier patch. I've fleshed out 
more documentation on using Bugzilla. The next time the site is updated 
it should be available on the site. Until then, update your cvs checkout 
and take a look at the following document in your browser.

/commons/math/xdocs/developers.xml

It has several simple bugzilla links that make it simpler to submit a 
bug/patch into the math project bugzilla.
