[authors] Update on Creating Formulas and Using Functions

[Stigant Fyrwitful]

I've been very quiet for the last several weeks, so I thought I would 
take a moment and give an update.  I've set a target date for myself to 
have a first draft of this chapter available for review on August 10.  I 
work better under pressure.  Currently, I'm just about finished with the 
prose and examples for the 'Creating Formulas' section and well underway 
on the 'Fixing Errors' section.  The 'Using Functions' needs a lot of 
work.  I've got quite a few examples laid out, but little prose written.

As far as problems go, my biggest problem is creating figures or 
diagrams that effectively illustrate the point that I'm trying to make.  
Currently, I am simply creating screen shots showing the progression 
consistent with the prose.  Perhaps, simple is better . . . . We'll 
see.  I don't suppose that we have a graphics editor on our 'editorial 
staff'.  Silly of me to ask.
