Nested Table Component for Blackberry

Based on our last Simple Table component, I have put together a Nested Table as well. The main features are:

-Each row can be rendered like an irregular table
-Each row is backed by an object
-Possibility to add a popup to row click

These classes demonstrate how to use the component:
SampleApplication.java
SampleRowBackingBean.java
SampleBean.java

You would need the following classes to make this work:
BNestedTable.java
BMultiRowBackingBean.java
BGenericTableCallback.java
BAbstractRowRenderer
BNestedRowRenderer.java
BSimplePopupScreen.java
FieldCreatorUtility.java
UiProperties.java

Possible improvements:
-implementing varying row heights
-implement table header, table footer and column header
