Java eXPerience FrameWork SvnCode

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.

Corrected a typo in javadoc comment.

Updated javadoc comment.

Incorrectly contained a wrong import statement that broke the build.

Corrected a serious error in Database that resulted in returning null instead of a single row result.
This involved the execueQuerySingleRow..() methods.

Changed OracleDatabase to get the time using a timestamp. The current implementation returned no time.
This could be due to the fact that Oracle 11 is used or a Oracle driver is used now instead of a Bea driver.

Explicitly used a US locale to make methods independent of the current regional settings.
