32    * Constructing a PagingScrollTable from GWT's Incubator is complicated. This class uses the Builder
33    * Pattern to simplify it. All public methods, except build() return a reference to the builder
34    * so methods can be chained; these methods can be called in any order.
35    * Calling build() at the end of the chain returns the constructed PagingScrollTable
36    * {@code
37    * pagingScrollTable = new PagingScrollTableBuilder<Person>().tablePixelSize(220, 200).cacheTable(10, 10).
38    * columnDefinitions(createColumnDefinitions()).build(new PersonDTOs().getPersons());
39    * }
40    * Parameterized type is the Data Transfer Object type which contains a row's data
41    *
42    * Column Definitions map a table column to a dto's field and set column header
43   
44    *
45    * PagingOptions are the paging widget. It is created after the builder creates the table and
46    * may be positioned anywhere.
47    * @see com.google.gwt.gen2.table.client.PagingOptions
48    *
49    * RowSelectionHandler is added after the builder creates the table.
