Helper to calculate the value of a Bbit mask as an instance of the unsigned type T. More...  
Extend the sizerelated traits with functionality operating on the specific types.
Specifically, provide the ability to bitreverse a value stored in the low bits of a word. This supports the requirements of a reflected (LSBfirst) algorithm.

Helper to calculate the value of a Bbit mask as an instance of the unsigned type T.
Need this evaluated at compiletime, supporting both cases where T can represent strictly more bits than are needed and where T represents exactly that many bits.
T  an unsigned integral type. 
bits  the number of bits to be masked. If bits is greater than the number of bits representable in T undefined behavior may result.
