Hmmm, I'm not sure about this.  Do we know for a fact that a bool variable
will always contain 1 or 0?  I've never seen code trap on an un-initialized
bool.  It seems that even an uninitialized bool corresponds to true or 
false.

Perhaps part of the problem is that I used 0 and 1 for bool variable
in order to not included english strings "true" and "false" in text files
and to save space.

I'll think about this.
