OK, so header files can be generated. The thing is though, when I am 
designing at the code level, I start with the declarations (such as class 
data members and methods) and do the implementation (or one can hand it off 
to someone else) afterwards. That serves as the "blue print" for further 
development and remains as first level of documentation as well. Working 
with just "implementation files" seems to be putting the cart before the 
horse. While eliminating something unnecessary is something to strive for, I 
don't think header files are unnecessary in the development process (i.e., I 
don't think that relegating them to just the situation given with my OP is 
good, exactly for the reasons of usefullness I gave).
