NEW FixtureContext (#2)
Added phpunit dependency, avoid clashes with existing PEAR installs

Tries to include Yaml/Inline class from two separate locations,
which clashes with "cannot redeclare class"
Use FixtureFactory for YAML, move helpers to FixtureContext, consistently create assets
Step transformations rather than special case step overrides
Delay UI interactions after ajax to allow browser rendering
