Allow steps to call context.skip\!(msg) to skip indexing of a record
Check for context.skip? on every iteration?
Added simple array writer (for easily testing what contexts are produced)
Merge branch 'array_writer' into skip_records
Merge branch 'master' of http://github.com/jrochkind/traject into skip_records
Add tests for skip!
Removed array_writer; not needed here
Don't need to test array writer, either :-)
Merge pull request #23 from jrochkind/skip_records
