Initial line strip/join transform

Destination must be a stream, defaulting to process.stdout. Opening
files is out of scope for this module.

Future constructor options will be accessible via CLI flags in the
convenience wrapper binary, bin/t.js.
Use object as intermidiate form

Timestamp each line, using timeStamp option to control if timestamp is
rendered in the text and JSON formatters. When rendered, timestamp is
stringified in ISO8601 format using moment.js.

Initial formatters include basic text and JSON.
Add line joiner for multi-line log messages

Uses a rolling 10ms window for flushing its buffer, performs
accumulation after objectification to negate impact on timestamps.

Line merging is optional and is disabled by default.
Add example to README.md
Add support for static line tagging

Supports strings or k/v objects at the moment
