Java eXPerience FrameWork SvnCode

Corrected a typo in a javadoc comment.

org.jxpfw.jsp.AbstractJSPBean::setMode(...)

Corrected some typos and put some code on one line. No harm done.

Made the setMode(...) method protected.
Using WebLogic 10 with JDK 1.5 suddenly resulted in calling this method, leading to a
java.lang.ClassCastException: java.lang.String.

Documented that the last digit in the result returned by squareRoot(...) may be off by one.

Updated unit test to take into account that the resulted rooted may differ in the last digit.

Added a new CBigDecimal.
Changed squareRoot method in CBigInteger to use integer operations only.
This made the method much faster.
Updated unit tests for the suareRoot() methods.

Finished the abstract writer and created a concrete subclass as an example
that can actually be used in practice.

First draft of a generic class for creation of csv output.
This is work in progress! Actually doesn't do anything yet!

Added propertyToGetMethod method and a unit test for this new method.
