Responsible for managing a Dashboard, updating it based on received messages, and periodically flushing it to output.

The Pulsar module is the client API for creating and updating jobs.

The :pulsar application defines two configuration values:

• :flush_interval - interval at which output is written to the console

• :active_highlight_duration - how long an updated job is “bright”

Both values are in milliseconds.

Updates to jobs accumluate between flushes; this reduces the amount of output that must be written.
