Looks good to me! I wouldn't worry too much about the travis failure for now, something to fix on |

I filed a bug on that, in case you didn't see me on IRC: |

The PR features a basic APM implementation, using Matt Mahoney's "bbb.cpp" as a reference. Gate is
operational but slow due to the lack of function-generated fixed-size tables (to be fixed when Rust matures). We can have tables if we restrict the
WideProbabilityandFlatProbabilitysizes to 4K (the tables are in commit history for that reason).APM allows for flexible context mixing when coding bits, and is successfully used for BWT output encoding by "bbb" and "https://github.com/IlyaGrebnov/libbsc".
