This is useful to track states or values in child handler. some documentation added. New doxygen group for interfaced added.

/**
|
||
* @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: There’s 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.
|
||
*

||
* \ingroup interfaces
