- Revise all exposition

- Eliminate @Configuration class
- Convert tabs to spaces in .java and .xml files
- Preserve empty directory structure in 'initial'
Fixed some small issues that made the 'start' version not runnable at the end.
The 'start' version has missing bits in the pom.xml as well as differences in what
the guide said. After comparing with 'complete', made the fixes and updated the
guide appropriately so it should work top-to-bottom if you use 'start' and really
copy-n-paste your way along.
