It would be cool to have a streaming like feature where new log entries are automatically pulled from CloudWatch. This feature could be activated using an option --stream. It should be considered that CloudWatch has some limits regarding the requests to its API, so polling every 100ms might be too much. I think 1s is okay.

If using a non-empty filter pattern, exceptions won't be shown in the output.

Example error logging:
In Java:
logger.error("Unexpected exception.", ex)

converts to CloudWatch logs

2017-06-23 09:00:00 <...> ERROR ExampleClass:123 - Unexpected exception. java.lang.IllegalStateException: ...

In this case the second line won't be shown in lambdalogs.

In some cases the order of log entries differs to the order in CloudWatch. This happened to me when the time was equal to a few other log entries, i.e. they all had '09:12:34' for example.

The entries are ordered using timestamps in milliseconds. Maybe there is an error in the script or the timestamp values are not like expected.

Extract a function with a separate API so that lambdalogs can be used as a CLI tool as well as a module in another module.
