Start with the conversion of indexed examples to ones that are associated with

a gofpdf method. This involves changes mostly in the test source file, but also
references in the main source files. After this conversion is complete, the
docWriter routine and interface can be scrapped. The current scheme will be
more straightforward for programmers using the library.
