New creates 2 loggers (plain and sugared) as global variables according to the desired loglevel ("DEBUG", "NOOP", "TEST", default is "INFO").

OnExit should be deferred immediately after calling the New() method.

We repeat this constant here as we don't want the circular dependency of importint our tracing package.

Resource - the counter is initialised with a zero value which indicates that the uber correction is made (default).

so we dont have to import zap everywhere.
