Bit-Vector Constructor

This macro creates encoded BitSlice buffers at compile-time, and at run-time copies them directly into a new heap allocation.

It forwards all of its arguments to bits!, and calls BitVec::from_bitslice on the produced &BitSlice expression. While you can use the bits! modifiers, there is no point, as the produced bit-slice is lost before the macro exits.
