/**
* @brief
* Interface for component which uses actions
*
* @details
* This interface is used to execute actions in the component. Actions, in the sense of this interface, are activities with a well-defined beginning and
* end in time. They may adjust sub-states of components, but are not supposed to change
* the main mode of operation, which is handled with the HasModesIF described below.
*
* The HasActionsIF allows components to define such actions and make them available
* for other components to use. Implementing the interface is straightforward: Theres a
* single executeAction call, which provides an identifier for the action to execute, as well
* as arbitrary parameters for input. Aside from direct, software-based
* actions, it is used in device handler components as an interface to forward commands to
* devices.
* Implementing components of the interface are supposed to check identifier (ID) and
* parameters and immediately start execution of the action. It is, however, not required to
* immediately finish execution. Instead, this may be deferred to a later point in time, at
* which the component needs to inform the caller about finished or failed execution.
*
