CHANGELOG

@ -14,3 +14,15 @@ a C file without issues
- It is now possible to change the message queue depth for the telecommand verification service (PUS1)
- The same is possible for the event reporting service (PUS5)
- PUS Health Service added, which allows to command and retrieve health via PUS packets
### Device Handler Base
- There is an additional `PERFORM_OPERATION` step for the device handler base. It is important
that DHB users adapt their polling sequence tables to perform this step. This steps allows for aclear distinction between operation and communication steps
### Events
- makeEvent function: Now takes three input parameters instead of two and
allows setting a unique ID. Event.cpp source file removed, functions now
defined in header directly. Namespaces renamed. Functions declared `constexpr`
now

/**
* @brief This is the access class for array-type data pool entries.
*
* @details
* To ensure safe usage of the data pool, operation is not done directly on the
* data pool entries, but on local copies. This class provides simple type-
* and length-safe access to vector-style data pool entries (i.e. entries with
* length > 1). The class can be instantiated as read-write and read only.
*
* It provides a commit-and-roll-back semantic, which means that no array
* entry in the data pool is changed until the commit call is executed.
* There are two template parameters:
* @tparam T
* This template parameter specifies the data type of an array entry. Currently,
* all plain data types are supported, but in principle any type is possible.
* @tparam vector_size
* This template parameter specifies the vector size of this entry. Using a
* template parameter for this is not perfect, but avoids
* dynamic memory allocation.

* The manager offers some adaption points and functions which can be used

*
* Please ensure that both initialize and initializeAfterTaskCreation are

*
* Users of the data pool use the helper classes LocalDataSet,

* a thread-safe and efficient way.
*
* The local data pools employ a blackboard logic: Only the most recent
* value is stored. The helper classes offer a read() and commit() interface
* through the PoolVariableIF which is used to read and update values.
* Each pool entry has a valid state too.

* @details
* Extends the PoolDataSetBase class for local data pools by introducing
* a validity state, a flag to mark the set as changed, and various other
* functions to make it usable by the LocalDataPoolManager class.
*
* This class manages a list, where a set of local variables (or pool variables)
* are registered. They are checked-out (i.e. their values are looked
* up and copied) with the read call. After the user finishes working with the
* pool variables, he can write back all variable values to the pool with
* the commit call. The data set manages locking and freeing the local data
* pools, to ensure thread-safety.
*
* Pool variables can be added to the dataset by using the constructor
* argument of the pool variable or using the #registerVariable member function.
*
* An internal state manages usage of this class. Variables may only be
* registered before any read call is made, and the commit call can only happen
* after the read call.
*
* If pool variables are writable and not committed until destruction
* of the set, the DataSet class automatically sets the valid flag in the
* data pool to invalid (without) changing the variable's value.

* The template class monitors mode and health state of its children
