Logger returns the structured logger.

Attempt at simplifying this whole logger in the context thing Could even make this take a generic map, then the logger that gets returned could be used just like the stdlib too, since it's compatible.

Initializers are functions that may set up the environment as they like.

WithLogger stores the logger.

HeadLinesWriter stores upto the first N lines in a buffer that can be retrieved via Head().

lineWriter will break apart a stream of data into individual lines.

TailLinesWriter stores upto the last N lines in a buffer that can be retrieved via Tail().

Errors that can be directly exposed to task creators/users.
