[authors] Updated Getting Started with Calc (Ch 7) -- need reviewers

[Richard Detwiler]

I have uploaded Getting Started with Calc (Ch 7) to the Feedback folder 
in the Getting Started folder.

I would like a few people to look this over, so see if there are any 
changes between 2.0.2 (the version that the current chapter is based on) 
and 2.2.
