Detailed Description

template<typename T>
class G::bit_iterator< T >

A bit-by-bit input iterator that extracts bits in msb-to-lsb order from a sequence of bytes.

Beware of basing bit_iterators on top of istream_iterators because istream iterators can extract from the underlying istream when they are advanced. This means that if the istream lives longer than the iterator then the istream will end up at a poorly-defined position. This bit_iterator implementation tries to delay the use of op++() to avoid this effect, but cannot do so for op==().
