[boost] [dynamic_bitset] Endianess and Adaption Vs Copying

I've noticed that the dynamic_bitset seems to have endian issues.  For masking
out the ith bit in a block, it uses 1 shifted left by i.  As a result, the bits
are not consecutive.  

For example if the block_type is uint8_t, and we have 16 bits in the bitset,
then bits are numbered:

00 01 02 03 04 05 06 07 15 14 13 12 11 10 09 08 

in memory.  That doesn't seem right---7th and 8th bits should be adjacent.  Does
anyone have suggestions for controlling this?

Second, has anyone adapted dynamic_bitset to be an adaptor for an existing
memory range to avoid copying?

Thanks!
