- now passes through LaTeX with fewer complaints.

- added note about braces for 'case' statements.

- could not formulate a sensible rule about when return statements
  need parentheses and when not.

- did not update codingStyleGuide.pdf ... I don't even know if it
  should be part of the git repo at all

- seems to work more reliably than the previous indented colons

- space between keyword and bracket in 'for(..)', 'if(..)', 'while(..)'

- use ':' to prefix verbatim code instead of #+BEGIN_EXAMPLE / #+END_EXAMPLE
  for a somewhat better feeling for the indentation.

- markup codingStyleGuide.org examples so they actually indent correctly

- use 'Info<<' as per codingStyleGuide instead of 'Info <<'
