[dwvqmhgd] Braille contraction based keyboard

Create an input method (e.g., soft keyboard) with which you can quickly type not just letters but words and partial words defined in Braille's grade 2 contractions.

The point here is to leverage the tremendous amount of work that has gone into defining a "good" set of contractions to compress English text.  The exact rules of Braille need not be followed: e.g., typing ho#ad, where # is the contraction for "the", still enters the word hothead, even though it wouldn't be proper Braille.

The alternative is to computationally derive a good set of contractions automatically from a corpus.
