    Description

      BitVector stores a single bit of data and it uses a bit of storage space. UInt1 is an alternate implementation which uses a byte to store a bit. Recently discovered bugs in BitVector and anecdotal evidence of performance issues seems to suggest that this code is slow and buggy. I am opening this bug to analyze the impact of replacing BitVector with UInt1.
