Detailed Description

Configuration of the LIPMStabilizer. This configuration is meant to be overriden from the RobotModule, and the user YAML configuration of the stabilizer task.

Note
Developper note: Do not change the default gains here, it is likely that robot modules and users do not override every single parameter value, and modifying their default might have serious consequences.
