Think it over.  I thought it worth pursuing even as I continued 
programming, and I really didn't put too much effort into it even with 
having started with no knowledge of the ov class members.  Sometimes 
when attempting a C++ coding feature it begins to feel not worth it. 
But in this case, I thought the routines were fairly straightforward and 
easy to debug.  In some ways, doing the programming in C is easier than 
trying to optimize in m-files because there is more flexibility. 
base2dec is used by bin2dec and hex2dec, so that makes it a good 
candidate for optimization.
