Re: [boost] Request for interest in new library : Bit Logic

As stated by another on the thread, these already exists for the  
integral types. using boost::lowest_bit I added : find_first,  
find_next functions. The website has been updated, and a new code  
drop placed with those functions implemented.

As for "most_significant_bit_index" I have not done that yet. Can you  
think of an example case where that would be helpful?

Thank you for the feedback.
