/**
* \brief This is the access class for array-type data pool entries.
* @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.
