Changes since 0.2.1:

New Features
---

- Tabu/SimulatedAnnealing samplers now use input state samples to
  initialize
- Racing context propagated to children via runopts
- Added `stoppable` class decorator to simplify implementing thread-safe
  stop behaviour
- Added `RoofDualifyDecomposer`
- Exposed all SA parameters in SimulatedAnnealing sampler
- Exposed non-interruptible Tabu timeout in Kerberos

Fixes
---

- Longer default runtime in Tabu
- Better handling of larger problems by Kerberos

Changes

  `ParallelBranches` in favor of explicit `Identity` block
