[DFDL-WG] Please review - New version of bit order/MIL-STD-2045 document

[Mike Beckerle]

I posted this to our documents.  http://redmine.ogf.org/dmsf_files/13300

This version is quite different. This version proposes that there are
actually two different variations on the least-significant-bit first
format.

One is where the bits are actually reversed (logical 0xE2 becomes 0x47 when
unparsed to a file)

The other is where the bits are simply interpreted as LSB first, but the
bytes are stored 'normally'. (0xE2 is in the file, but the 'first' 3 bits
of it are 010, not 111.)

Turns out it is this latter form that MIL-STD-2045 and related standards
need, and that the Daffodil code implements today.

I hope this version clarifies some things. You'll see there is a need to
come up with useful names for these concepts when you read the document.
