For situations where we don't want any logs produced by the application.
* Remove references to Logger from README
* Add implementation of DiscardLogger
Requiring the Logger be passed in to each of the structs was causing
Panics if the Logger was omitted.
* Add function for overriding the default logger
* Remove panics caused by initialization
To allow for different logging endpoints we'll introduce a Logger
interface that will be passed into the pipeline during initialization.
* Add Logger interface
* Use logger interface in pipeline and emitters
In some cases we'll want to save the data from the stream directly with
no transformation needed. This will allow us to return the raw data
string from the stream
* Add new StringToStringTransformer
* Remove Record from codebase in favor of more generic interface
Godoc removes un-exported fields and puts a line-break in the
documentation when exported fields and un-exported fields aren't grouped
together. Will follow this standard going forward.
Noticed GetRecords error when a Shard's lease expired.
* Added a timeout so we don't hit the rate limit on this type of error.
* Increased the timeout when there are no Records on the stream.
