Logahawk is a Java library designed to make logging easier for developers.

Specifically the library aims to do the following:

Simpler logging - straight-forward calls to the logger object
Better logs - automatic formatting of complex objects
Flexibility - interfaces for everything, anything can be changed
Compliment, not replace - Works with your existing logging framework

See Goals for a more in-depth explanation.

- Added HierarchicalLoggerRegistry to mimic how many logging frameworks provide access to Loggers.
- Added LoggerRegistry implementations for supported third-party logging framewors. (See Integration.)
Added ProxyLogger and ProxyListener to make implementing proxies easier. Existing class that use this pattern have been updated.

Added SeverityFilterListener based on SeverityFilterLogger.
Added LengthTruncatingListener and LineTruncatingListener to help keep log sizes under control.
