[Insight-developers] LOC

[Miller, James V (Research)]

I see a few suprises here...

1. I am little suprised at the number of lines of C code.  I guess most of
our header files are mistaken as ansi C code.

2. It might be better to run these statistics excluding the Utilities
directory
since we probably shouldn't take credit for things like vnl, png, jpeg, ...
I 
am suprised that ITK comes up to 1M lines of code.

3. The schedule estimate is suprisingly accurate.  However, the number of
developers is off by at least a factor of 2 (probably closer to being off 
by a factor of 3-4).

4. ITK was a bargin given SLOCCount's estimate project cost.
